Finding the Inverse Function of a Composite Function

The video tutorial explains how to calculate the inverse function of H, given that H equals the composition of two functions, F and G. The process involves substituting G into F, rearranging the resulting equation to isolate X, and then factorizing and simplifying the equation. The final step is to express the inverse function of H in terms of X. The tutorial also outlines the marking scheme for the problem, emphasizing the importance of each step in the process.
