Learn How to Write the Domain from the Composition of Two Functions

The video tutorial introduces an uncommon notation GFG FX and explains how to evaluate functions using this notation. It covers the process of composing functions, specifically focusing on plugging G of X into F of X. The tutorial also guides students on finding the domain of functions, emphasizing the importance of inequalities in determining valid input values.

What does it mean for a value to be greater than 1 in the context of the domain?

How do you determine the domain for the function 1 / sqrt(X) - 1?
