Inverse Functions and Operations

The video tutorial guides viewers through the process of finding the inverse of a function. It begins by replacing f(x) with y, then swapping variables and solving for y using inverse operations. The tutorial explains how to handle negative fractions by multiplying with the reciprocal to simplify the equation. Finally, it demonstrates how to express the inverse function in a simplified form.

What is the first step in finding the inverse of a function?

• Multiply by the reciprocal

• Solve for x

• Swap the variables

• Replace f(x) with y
