The video tutorial explains how to find the inverse of a function. It begins by replacing F of X with Y to facilitate algebraic manipulation. The tutorial emphasizes the concept of inverse operations, which involve reversing the original operations applied to X. The process includes solving for Y by manipulating the equation, such as multiplying and dividing terms, and handling square roots. Finally, the inverse function is expressed in proper notation, completing the process.
