Composing a quadratic function into a square root function

The video tutorial covers the concept of function composition, specifically plugging G(x) into F(x). It discusses domain restrictions, emphasizing that even after simplification, these restrictions remain. The tutorial explains the operations involved, such as the square root and distribution, and highlights the importance of considering domain restrictions in function composition.

How do you determine the values that make the denominator equal to zero in rational functions?

Discuss the importance of understanding domain restrictions when simplifying functions.
