How to evaluate a piecewise function when it contains a hole

The video tutorial explains how to evaluate functions at specific points, such as F(4), FA(-4), and F(0). It discusses the conditions under which different functions should be used and highlights the importance of not taking the square root of a negative number, which results in an undefined value. The tutorial also emphasizes the correct application of functions based on given conditions and provides a step-by-step approach to solving these problems.
