Ch 14: WEST Math: Absolute Value

About This Chapter

Get your absolute value skills in order with the video lessons offered by Study.com. This chapter can prepare you for any absolute value-related questions on the WEST Math exam.

WEST Math: Absolute Value - Chapter Summary

While the basic concept of absolute value is fairly straightforward, graphing absolute value equations and solving absolute value problems can get pretty tricky. This chapter can help you refresh your absolute value skills in quite a few areas, such as:

  • Reflections and dilations in absolute value graphs
  • Solving problems with operations inside and outside the absolute value sign
  • Understanding absolute value notation
  • Finding the absolute value of a real number

Our video lessons include plenty of easy-to-grasp examples and detailed solutions so you're always on the same page as our world-class math teachers. Take the short quiz at the end of each lesson to make sure you've mastered the necessary skills, and ask our teachers for help any time you aren't quite following a lesson.

WEST Math: Absolute Value Chapter Objectives

You'll need to pass the WEST Math exam to qualify for a math endorsement as a current or new teacher in Washington State. The exam has five main sub-areas and includes a total of 150 multiple-choice questions. Problems involving absolute value are included in the Patterns, Algebra and Functions sub-area, which makes up about 24% of the entire WEST Math exam. The video lessons here are designed to prepare you for any and all absolute value questions in this sub-area.

You can register for the WEST Math exam online, and it's offered throughout the calendar year at Pearson testing centers nationwide. You can also check seat availability for any date you're considering. The test is computer-based, and you're allotted four hours and 15 minutes for the entire exam. You need a score of 220 in order to pass, and you'll receive a score report immediately upon completion. You're free to re-take the exam if needed, though you'll need to wait 30 days before taking it again.

What is an Absolute Value?

1. What is an Absolute Value?

When we're talking and comparing numbers, we often don't care whether its positive or negative, just how big it is. This is often called the magnitude of a number and we find it by taking the absolute value. Learn all about it here!

Finding the Absolute Value of a Real Number

2. Finding the Absolute Value of a Real Number

You can find the absolute value of any real number. This lesson will define absolute value, explain what real numbers are and give the steps to finding the absolute value of any real number.

Solving Absolute Value Practice Problems

3. Solving Absolute Value Practice Problems

There are many easy mistakes to make when solving absolute value equations. Learn how to avoid those mistakes here by working on examples of absolute value equations with operations on the inside and the outside of the absolute value.

How to Graph an Absolute Value and Do Transformations

4. How to Graph an Absolute Value and Do Transformations

Absolute value graphs normally look like the letter 'V', but transformations can change that 'V' in a number of different ways. As well as teaching you how to graph absolute values, this video will focus on a specific group of transformations called translations. Learn all about what that means here!

Graphing Absolute Value Equations: Dilations & Reflections

5. Graphing Absolute Value Equations: Dilations & Reflections

Although a basic absolute value graph isn't complicated, transformations can make them sufficiently confusing! In this lesson, you'll practice different transformations of absolute value graphs.
