The video tutorial explains how to find and verify inverse functions. It begins by introducing the concept of inverse functions and the importance of switching the input and output values. The process involves changing F of X to Y, interchanging X and Y, and solving for Y. The tutorial also covers verifying the inverse by checking if the composition of the function and its inverse equals X. The explanation includes algebraic steps and examples to ensure understanding.
