How to Graph a Piecewise Function

The video tutorial explains how to graph piecewise functions by breaking down the process into steps. It covers rewriting expressions in y=mx+b form, identifying slopes and y-intercepts, and applying constraints to graph each segment. The tutorial demonstrates graphing three different lines with specific constraints, emphasizing the importance of shading only the valid parts of the graph.
