UNIT OVERVIEW

In this unit, you will explore functions and their inverses. Think of a function as a machine that transforms inputs into outputs. An inverse function reverses this process—it takes the output and gives back the original input.

You have worked with functions since Grade 10. Now you will deepen your understanding by learning what makes a function have an inverse, and how to find and sketch inverses for different types of functions.

By the end of this unit, you will be able to:
