Students will review:
This chapter helps students review the concepts in an Algebra II: Properties of Functions Review unit of a standard high school algebra II course. Topics covered include:
- Adding, subtracting, multiplying and dividing functions
- Domain and range
- Composing functions
- Inverse functions
1. What is a Function: Basics and Key Terms
In calculus, functions map one set of numbers of another set of numbers, such as calculating the price of something bought by the pound. Learn about the basics of a function, examples of functions utilized in everyday life, the definitions of key terms like domain and range, and how to create a function and graph it.
2. Transformations: How to Shift Graphs on a Plane
Transformations in mathematics are functions that change into different functions. Explore the different types of transformations including rotations, reflections, dilations, and translations, and learn how to shift graphs on a plane.
3. How to Add, Subtract, Multiply and Divide Functions
Basic mathematical operations such as addition, subtraction, multiplication, and division can be performed on functions. Explore cost, revenue, and profit functions, and learn how to perform the four function operations.
4. What Is Domain and Range in a Function?
The domain is the set of all the allowable input values of a function, while the range is the set of all possible output of the function. Learn how to find the domain and range of a function through given values, graphs, or general function rules.
5. How to Compose Functions
Function composition refers to integrating or the combining of multiple functions, often simplifying them in the process. Discover how the rules of functional notation apply to composing functions through two different example problems.
6. Inverse Functions
An inverse function is a function that undoes a previous function and is expressed with the power of negative one. Explore inverse functions, confirming inverses, finding inverses, and learn about the horizontal line test.
7. Applying Function Operations Practice Problems
Function operations, the collection of knowledge about how to compose and solve functions in different ways, can be combined to solve more complex questions. Learn more about function operations and apply the principles of inverse functions, domain, range, and function composition to solve three practice problems.
8. Congruent Polygons: Definition & Examples
In this lesson, you'll review what polygons are, and you'll discover the conditions that polygons must meet in order to be congruent. Then, you can test your knowledge with a brief quiz.
