Limits of Composite Functions

The video tutorial explores the limits of composite functions using the graphs of F(X) and G(X). It covers four main examples: the limit as X approaches -infinity, +infinity, zero, and -1. The tutorial explains how the outputs of F(X) become inputs for G(X) and how this affects the limits. It highlights the behavior of function values as they approach horizontal asymptotes or increase without bound, leading to conclusions about the limits, including cases where limits do not exist.
