About This Chapter
Evaluating Piecewise & Composite Functions - Chapter Summary
Strengthen your ability to evaluate piecewise and composite functions by watching this chapter's entertaining videos. The lessons examine ways to evaluate, graph, translate and more with piecewise and composite functions. Upon completion of this chapter, you will be ready to:
- Define piecewise functions
- Find the domain of piecewise functions
- Graph and translate piecewise functions
- Evaluate composite functions
- Solve equations for different variables and manipulate functions
The videos in this chapter average about 8 minutes apiece, providing you with access to mini lessons that are short and highly informative. Watch the videos in any sequence and as many times as needed to feel confident that you understand the materials. Scroll below the videos to access transcripts of the lessons if you'd prefer to review them in their text format. Find out how much you understand about the evaluation of piecewise and composite functions by taking multiple-choice quizzes and a chapter exam.
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. How to Evaluate Composite Functions
Sometimes a math function depends on the outcome of another function. This lesson breaks down this chain reaction, called a composite function, and how to evaluate them.
6. Manipulating Functions and Solving Equations for Different Variables
Functions can be manipulated to solve for many different variables. There are certain rules to follow, but if the rules are adhered to, solving equations can be quite simple. This lesson will show you how.
