Find the Domain by Composing Two Functions Radical and Rational

The video tutorial explains how to compose functions, specifically G(F(X)), and discusses the importance of understanding radical operations. It reviews how to break down square roots into numerators and denominators and emphasizes the need to consider domain constraints, particularly when dealing with square roots and denominators. The tutorial also clarifies how to represent domains correctly, using parentheses instead of brackets when necessary, and addresses student questions to ensure understanding.

Why can't X be equal to 1 in the domain?

Describe the domain of the function as concluded in the text.
