Inverse Functions and Their Properties

The video tutorial covers the concept of inverse functions, focusing on verifying them through composition. It explains how to determine if two functions are inverses by plugging one into the other and simplifying to x. The tutorial includes examples with linear, quadratic, and square root functions, demonstrating both successful and unsuccessful verifications. It also discusses ordered pairs, highlighting how the domain and range switch in inverse functions, and differentiates between functions and relations.

What is the main method used to verify if two functions are inverses of each other?

• Checking the domain and range

• Solving equations

• Using composition of functions

• Graphing the functions
