Compose a linear function into a square root function

The video tutorial explains the function G of X and how to evaluate it with different inputs. It introduces the concept of function composition using H of X and discusses the importance of domain restrictions in compositions. The tutorial also covers how to find domain restrictions for radical functions, emphasizing the need to consider the original function's domain when composing functions.
