The video tutorial explains how to find the inverse of a function. It begins by introducing the concept of inverse functions and their purpose, which is to reverse the operations of the original function. The tutorial then guides viewers through writing the original function in terms of x and y, interchanging these variables, and solving for y to derive the inverse function. The process involves cross-multiplying and factoring to isolate y. Once the inverse function is determined, the tutorial demonstrates how to calculate the inverse of a specific value, f inverse of 8. The video concludes with a summary of the steps and the importance of understanding inverse functions.

In the example provided, what is the original function expressed as?

• Y = (X + 1) / (X + 3)

• Y = (X + 3) / (X - 1)

• Y = (X - 1) / (X - 3)
