How to evaluate for three different values of a piecewise function

The video tutorial explains how to evaluate functions with multiple inputs by considering domain constraints. It covers examples of evaluating functions for specific inputs, emphasizing the importance of choosing the correct function based on the domain. Common mistakes, such as plugging values into both functions, are highlighted to help students understand the correct approach.

What are the three different values that need to be evaluated?

Explain how to choose between the two functions based on their domain.

How do you evaluate f of negative 2 using the given functions?

What is the constraint on the first function regarding the input values?

Describe the mistake students often make when evaluating functions with different constraints.
