Learn to evaluate a piecewise function

The video tutorial explains piecewise functions, which are composed of two different functions with specific constraints. It highlights the importance of constraints in determining which function to use based on the value of X. An example is provided to demonstrate how to evaluate a piecewise function when given a specific input, such as F of -2.

Calculate F of -2 using the appropriate piecewise function.

What is the result of F of -2 and how is it derived?
