 ## Algebra C Math: Function Inverses

This topic teaches the student the fundamentals of function inverses. The student learns about one-to-one relationships. Then, they learn how to show functions are inverses. Finally, the student learns how to find the inverse of linear and cubic functions.

This series of four lessons instructs the student on the principles of inverting functions.

### One to One Relationships

This lesson introduces the student to one to one relationships. The student learns how to utilize the horizontal and vertical line tests to determine the relationship between two variables on a graph.

### Showing Functions are Inverses

In this lesson, the student learns how to show two functions are inverses. The student learns that if the composition of the functions is equal to the variable, then the functions are inverses of each other.

### Finding the Inverse of Linear Functions

This lesson shows the student how to find the inverse of a linear function. The basic idea behind finding the inverse of a function is demonstrated and the student learns how to use this process to find the inverse of linear functions.

### Finding the Inverse of Cubic Functions

In this lesson, the student learns how the process of finding the inverse function can be used to find the inverse function of a cubic equation.
