NES Math: Piecewise Functions - Chapter Summary
Let us help you review information on working with piecewise functions as you prepare for the NES Math test. Our lessons, quizzes and other tools can help you get ready for questions on the following:
- Definition of piecewise functions
- Ways to determine the domain of piecewise functions
- Graphs of piecewise functions
- How to translate piecewise functions
You'll get practical experience working with piecewise functions in these lively video lessons, developed and taught by experts in the field. The lessons are available anytime, via computer or mobile device. Study aids include short lesson quizzes, a text transcript with key terms in bold type and a clickable Timeline that makes it easy to return to specific parts of the lesson for review.
NES Math: Piecewise Functions Chapter Objectives
Five states have made passing the NES Math test one of the requirements for certification to teach secondary-level math. The test's questions are divided into five content domains, and questions on the material covered in this Piecewise Functions chapter are in the Patterns, Algebra and Functions test domain. This is the largest content domain on the NES Math test, accounting for 24% of the total score.
All questions on the NES test are multiple-choice, as are the questions on the quizzes that follow each of our lessons and the comprehensive chapter exam. Our tests give you a good opportunity to find out what it will be like to answer questions on the NES 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.
