Graphing Step Functions

This video tutorial explains how to graph step functions by understanding their general shape and constraints. It covers the use of closed and open circles in graphing inequalities and provides examples of graphing step functions with specific constraints. The tutorial also highlights common mistakes made when graphing without considering constraints and concludes with a summary of the lesson.
