Dividing two functions then determine the domain

The video tutorial explains how to determine the domain of a function composition, specifically F of G of X, by dividing F of X by G of X. It highlights the importance of understanding domain restrictions, such as not dividing by zero and not taking the square root of a negative number. The tutorial demonstrates solving inequalities to find domain restrictions and uses interval notation and graphing to represent the domain visually.

What does the inequality X - 4 < 0 represent in terms of the domain?

How is the interval notation for the domain expressed based on the discussion?
