Step by step learn how to write the inverse of a function and determine if a function or not

The video tutorial explains the process of finding the inverse of a function. It begins by replacing F of X with Y, then swapping the X and Y coordinates. The next step involves solving the equation using inverse operations, such as multiplying by the reciprocal instead of dividing by a fraction. Finally, the tutorial verifies if the inverse is a function by checking if each input results in a single output.
