How to find the inverse of a function then determine domain and range

The video tutorial explains how to identify the domain and range of a function, find its inverse, and handle square roots. It begins with identifying the domain, followed by steps to find the inverse by swapping variables and solving for Y. The tutorial emphasizes the importance of considering both positive and negative values when introducing square roots. Finally, it covers determining the domain and range of radical functions, ensuring the values inside the radical are non-negative.

What is the significance of introducing the square root in the function's analysis?

How do you derive the range from the domain in the context of the function discussed?
