THEA Test: Properties of Functions - Chapter Summary
As you study for the THEA test, you want to feel confident that you know what to expect. The video lessons in the chapter can prepare you for questions that address the properties of functions by helping you:
- Understand the basics and key terms of a function
- Know how to add, subtract, multiply and divide functions
- Grasp the meaning of domain and range in a function
- Compose functions
- Write and find inverse functions
- Apply function properties to solve complex problems
Use the lessons to create a study guide specifically dedicated to the properties of functions or add to your broader math study guide. In addition to reviewing the videos, you can study for the test by printing transcripts in order to take notes or highlight key concepts.
THEA Test: Properties of Functions Chapter Objectives
The THEA test is an Internet-Based Test (IBT) that is broken into three sections. Each section assesses your comprehension of a different subject area. Topics in this chapter are found in the mathematics section, which consists of 50 multiple-choice questions. Scored separately from the other sections, the math section has a minimum passing requirement of 230. Earning or exceeding that score increases your chances of gaining admission into the Texas public college or university of your choice as an incoming freshman.
To reduce the stress of preparing for this test, review the lessons in this chapter, then test your understanding by taking self-assessment quizzes. A chapter exam is available to gauge your comprehension of all of the lessons. Any questions you have about lesson topics can be submitted to our experts.
1. What is a Function: Basics and Key Terms
Mapping numbers sounds complex, but we do it when we buy gasoline. We pump gasoline, and the gas station charges us based on the amount of gas that we pump. Learn how this relates to functions while reviewing the basics and notations in this lesson.
2. How to Add, Subtract, Multiply and Divide Functions
Adding, subtracting, multiplying and dividing functions is about as simple as substituting in expressions and then just doing whichever operation it asks you to do. Check out this video lesson to see some examples of this and learn just how easy it is!
3. What Is Domain and Range in a Function?
The domain and range are the possible outputs and inputs of a function. In this lesson, learn about what might restrict the domain and how to figure out the domain and range from a graph.
4. How to Compose Functions
Function composition is the process of putting two or more functions together. This video lesson will explain how this process works and also show you how to evaluate functions that have been composed.
5. Inverse Functions
Inverse functions are two functions that do exactly opposite things. Check out this lesson to learn about how to write inverse functions, find inverse functions, and predict whether or not they exist.
6. Applying Function Operations Practice Problems
In this lesson, learn how to apply all the different properties of functions to solve complex problems. From function operations and composition to domain and range, get your practice here!
