How to write the inverse of a function when it is a fraction

The video tutorial explains how to find the inverse of a function, starting with identifying domain restrictions. It details the process of replacing F(x) with Y, swapping variables, and solving for Y by getting variables on the same side. The tutorial covers factoring and simplifying the equation to isolate Y, and concludes with determining the domain of the inverse function, including inherited restrictions.

Explain the significance of having variables on the same side of the equation.

What is the final domain of F inverse of X as stated in the text?
