How to evaluate a piecewise function

The video tutorial explains how to understand and evaluate functions with and without constraints. It covers the concept of piecewise functions, emphasizing the importance of using the correct function based on the domain constraints. The tutorial also highlights common mistakes students make, such as using both functions in piecewise scenarios or choosing the wrong function for a given domain.
