Verifying Inverse Functions in Algebra 2

The video tutorial explains how to verify if two functions are inverses of each other using composition. It demonstrates the process with examples, showing how to substitute one function into another and check if the result is x. The tutorial also covers cases where functions are not inverses, highlighting the importance of the result equating to x for both compositions.

What is the primary method discussed for verifying if two functions are inverses of each other?

• Using derivatives

• Function composition

• Graphical analysis

• Limit comparison
