# Ch 22: OAE Mathematics: Piecewise Functions

### About This Chapter

## OAE Mathematics: Piecewise Functions - Chapter Summary

Watching this chapter's online video lessons can show you how to identify and implement piecewise functions as well as how to perform other operations. For example, the videos illustrate the steps for writing piecewise functions and translating graphs. Use what you discover to answer OAE Mathematics examination questions. This chapter aims to help you review how to:

- Define and provide examples of piecewise functions
- Determine a function's domain
- Graph a piecewise function
- Translate functions by shifting, reflecting and stretching them

This chapter's online video lessons discuss these topics in detail, and they could help you answer questions on piecewise functions when you sit for the OAE Mathematics examination. You can study anytime or anywhere as long as you have access to a web-ready device. Get the most out of the videos by taking the quizzes that follow each lesson.

### OAE Mathematics: Piecewise Functions Chapter Objectives

Your ability to understand and analyze piecewise functions, along with other mathematical concepts, will be evaluated on the Patterns, Algebra and Functions section of the OAE Mathematics examination. This second section of the five-part test accounts for 24% of the score. Answer the computer-based examination's 150 total multiple-choice questions in the allotted four hours and 15 minutes as you seek a mathematics endorsement in Ohio.

### 1. What are Piecewise Functions?

A piecewise function is a certain type of function that is made up of different parts. This lesson will define and describe piecewise functions and teach you how to identify them and how to write them.

### 2. How to Find the Domain of Piecewise Functions

The domain of any function is all the values that x can be for that function. Piecewise functions are special functions that have different parts with unique rules for each part. This lesson will show you how to find the domain for piecewise functions.

### 3. How to Graph Piecewise Functions

Piecewise functions are specific functions that have more than one piece. There is a special trick to graphing these type of functions, which you will learn in this lesson.

### 4. Translating Piecewise Functions

Piecewise functions are two or more functions that only use part of a domain. If these functions need to be changed, we can translate them without even having to know the equation.
