Multiply two functions with radicals and find the domain

The video tutorial explains how to combine functions and simplify expressions, focusing on the function F of G of X. It then delves into finding the domain of the function, considering the restrictions imposed by radicals in the denominator. The tutorial covers solving inequalities and the importance of sign flipping when dividing by negative numbers. Finally, it uses a number line to visually represent the domain, highlighting the valid range of X values.
