Learn how to step by step find the inverse of a quadratic function

The video tutorial explains how to find the inverse of a function. It begins by replacing F of X with Y, then swapping the X and Y variables. The next step involves solving for Y using inverse operations, such as undoing addition and subtraction, and taking the square root. Finally, the tutorial concludes by replacing Y with F inverse of X, resulting in the inverse function F inverse of X = ± sqrt(X + 3).
