Inverse Functions and Operations

The video tutorial explains how to write inverse functions by understanding the order of operations. It emphasizes using a two-way table to avoid mistakes. The instructor provides three examples, demonstrating how to reverse operations to find the inverse function. Each example involves different operations, and the final example includes simplification.

What is the primary purpose of an inverse function?

• To add a constant to the original function

• To undo the operation of the original function

• To perform the same operation as the original function

• To multiply the original function by a constant
