This section explores the process for finding inverses of functions, and then proving the function and its inverse algebraically. Additionally, it explores how the graphs of functions and their inverses compare to each other, and it investigates how to use the horizontal and vertical line tests to determine if the inverse is itself a function or not.

In the story, Alexander, Who Used to Be Rich Last Sunday, Alexander receives a dollar from his grandparents that he plans to save, but he spends it all, a little at a time. In this lesson, students count by 2s to fill a container with 100 pennies. They are asked whether 100 pennies is the same amount of money as one dollar. They listen to the story, and as Alexander spends his money, students come up and remove the correct number of pennies from a container. At the end of the story, students are again asked if 100 pennies is the same amount of money as one dollar. Students discuss the choices that Alexander made and give advice on how he could save his money to reach his goal of buying a walkie-talkie.
