Evaluating a piecewise function with transformations

The video tutorial explains how to evaluate functions at specific points using domain knowledge and graphs. It covers evaluating F(0), F(1), and F(2) by identifying the correct function based on domain constraints. The instructor emphasizes common mistakes students make, often due to lack of attention or absence from class.

How does the teacher suggest students should approach understanding the graph and its functions?
