# Ch 18: FTCE Math: Piecewise Functions

### About This Chapter

## FTCE Math: Piecewise Functions - Chapter Summary

If you're scheduled to take the FTCE Math examination, allow this chapter's video and text lessons to help you understand and write piecewise functions. Learn or review the process of shifting, stretching and reflecting piecewise functions, and discover the rules for naming piecewise functions that are unknown. Explore the differences between the greatest and least integer functions, and become proficient at evaluating a piecewise function through this chapter. As you finish, you might be able to:

- Identify piecewise functions
- Graph, translate and calculate the domain of a piecewise function
- Provide examples of a step function

This chapter's lessons are taught by credentialed mathematics professionals whose aim is to help you learn the fundamentals of piecewise functions. Check out each of the lessons on your handy tablet or laptop before you sit for the FTCE Math examination. The visual lessons offer video tags and entertaining animation. The text transcripts contain detailed explanations as well as examples of functions and equations. Test your knowledge and memory with the short multiple-choice quizzes.

### 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.

### 5. Step Function: Definition, Equation & Examples

In this lesson, we'll learn what a step function is and become comfortable with this type of function. We'll examine common examples, such as the floor and ceiling functions and the heaviside function.
