**Key Algebra Questions Vocabulary Reference Sheet 2 Regents**

When we think of math, we usually don't think of vocabulary. However, incorporating vocabulary into Algebra 2 Regents exercises is an effective way to increase your confidence on the exam and improve your score.

We analyzed published Algebra 2 Regents exams to find the most important vocabulary to study. Our vocabulary cheat sheet gives you the words and phrases you need to know.

### 1. If your message says**INTEREST,**Think exponential growth.

Algebra 2 students are probably already familiar with the simple compound interest formula, but that's not the interest rate you need to know for the Algebra 2 Regents exam.

Rather, you need to meet them.**compound interest formula**for the Regents Algebra 2 Exam.**NO**one of the equations listed inAlgebra 2 Regents Formula Sheet, so take the time to study this formula.

keep this in mindArepresents the final value,PAGrepresents the original principal amount,Ris the interest rate as a decimal number,norteis the frequency with which interest is compounded per period, andTis the number of elapsed periods.

Example question:

### 2. If your message says**REVERSAL,**Consider changing your variables.

In Algebra 2 you will learn about the existence of**inverse functions,**or functions that are inverses of each other. We can express the inverse of a functionf(x)withf^{-1}(x).

The easiest way to find the inverse of a function is to change that function's variables. For example, the reverse ofy=6x+2is easyx=6y+2. Note that the only difference is that thexjjVariables have switched places.

If your message asks about inverse functions, you may need to use inverse operations to isolate the dependent variable in the inverse function.

You can check if you found the correct inverse of a functionCheck out our calculator hacks below.

Example question:

### 3. If your message says**NORMAL DISTRIBUTION**, remember the rule of thumb.

A tricky concept in Algebra 2 rulers is the normal distribution and standard deviation. This is another fact to know if you are cold how is it**NO**about itAlgebra 2 Regents Formula Sheet.

AND**Golden Rule**essentially states that if the data has a normal distribution:

- About 68% of the values are within one standard deviation of the mean.
- About 95% of the values are within two standard deviations of the mean.
- About 99.7% of the values are within three standard deviations of the mean.

If you remember these three percentages, you can solve standard deviation problems without having to do any real calculations.

You can alsoUse our Standard Deviation Calculator Trickto solve problems and review your work.

Example question:

### 4. If your message says**SEQUENCE**Ö**SERIES**, get your formula sheet.

Algebra 2 Regents contains many sequence and series questions. Lucky for you thatAlgebra 2 Regent Equation Sheetcontains the formulas needed to solve these types of problems.

The trick is knowing when to use which equation. Consider your options:

If your problem involves a list of terms or a specific number of terms in a list, you are dealing with a**Sequence.**There are two types of sequences:**geometric**j**Arithmetic.**

If the terms are a list extended by a common difference, their order is arithmetic. Can you remember why you are*Add to*to get each additional term and "add" and "arithmetically" start with A. When terms increase in a common proportion, their order is geometric.

If you need to identify the sum of terms in a list, consider a**Series**and you need to use the series formula.

Example question:

*Source:**Algebra Regents Test 2 January 2019 Question #4*

### 5. If your message says**PERIOD**Ö**AMPLITUDE**, think of graphs of trigonometric functions.

Working with trigonometric functions and their graphs is likely to be a new experience for Algebra 2 students. Two key terms that appear frequently on the Algebra 2 Regents exam are**Period**j**Amplitude,**So familiarize yourself with what this means in terms of trigonometric functions.

Consider the graph of a trigonometric function:

AND**Period**is the horizontal length of one complete "cycle" of the function, or the distance between equivalentsjValues.

AND**Amplitude**is half the distance between the maximum and the minimumjValues.

There's a lot more to know about trigonometric functions, but understanding these two vocabulary words will give you a head start on the Algebra 2 Regents exam.

**3 Strategies and Tips for Multiple Choice Questions in Algebra 2 Regents Exams**

### 1. Use the removal process

Whenever you are faced with a wide range of possible answers, it can be helpful to cross out all possible answers that you know are incorrect. This is called the "process of elimination".

For the Algebra 2 Regents exam, you will be given 4 possible answers to all multiple choice questions. It is very likely that you can easily eliminate at least one, and perhaps even two, of the possible answers. As you go through each possible answer choice, literally draw a line through each answer choice.**he must**it's wrong.

If you can't decide on a definitive answer, take a guess or try a new strategy. Whatever you do, don't leave any question unanswered on your regents exam. You don't lose credit for an incorrect answer, so just guessing is much better than leaving something blank.

What makes the removal process such a great hack?

You originally start with a 25% chance of randomly guessing the correct answer (1 out of 4). If you can eliminate two of the possible answers, that means you've doubled your chances of getting the question right to 50% (1 in 2)!

### 2. Constantly ask yourself, "Is my answer logical?"

Finding sensible answers is especially important when solving word problems or real-life application problems. When you think you've found your definitive answer, stop for a moment. Check that your response makes sense given the situation in the message.

Think to yourself, "Does my answer make sense?" or "Is my answer logical?"

For example, if a question asks you to find the slope of a line that descends from left to right on a graph and you choose a positive slope, your answer will be unreasonable because of the slope of that line.**he must**be negative.

### 3. Don't get stuck on a single problem

Most students have enough time to answer all of the Regents Algebra 2 exam questions. In fact, most students have too many minutes left in the 3 hour time frame!

However, that doesn't mean you should "get stuck" on a single multiple-choice question while working on the exam. It's important to stay confident and focus on the issues you know very well. You can always go back to the tough questions and spend more time thinking through different options. In fact, we often get new ideas for solving complicated problems simply by working on other problems elsewhere in the exam.

We typically recommend around 3 minutes for each multiple choice question. For more details on how the exam works, seeCheck out our complete Algebra 2 Regents review guide.

**3 Strategies and Tips for Answering Built-in Questions on Algebra 2 Regents Exams**

### 1. Don't be lazy (show your work)

One of the best parts of constructed answer questions is that you can get partial points for questions even if your final answer is not correct.

To earn partial credit, it is imperative that you show as much work as possible on each Constructed Response question. This means that you should always write down anything that you feel is relevant to solving the problem. The more accurate the work you demonstrate in your test book, the more likely the test evaluator will be able to recognize you.

### 2. Answer ALL parts of the question

The built-in response questions on the Algebra 2 Regents exam often have multiple parts.

For example, read this 4-point question from an actual Regents exam:

*Source:**Algebra Regents Test August 2, 2019 Question #33*

You must answer BOTH parts of this question for full credit. A helpful tip can be to skim through each question in Parts II, III, and IV of your test before taking it to make sure you haven't skipped any part of a question.

### 3. Start with your strengths

Some students like to read all of the answer prompts built into their Regents exam before writing the answers. When Part II of the exam begins, quickly go over all the questions in Part II. This can be helpful as it allows you to find the questions you feel most confident with and remove them first.

You'll feel motivated when you start with the constructed response questions, and you'll have more time for questions that take longer to solve. If you decide to answer the questions in your own order for the test, simply be sure to answer all the questions provided.

*Remember: you should never leave a constructed answer question with a blank answer.*
