Graphing Piecewise-Defined Functions

This video tutorial teaches how to graph piecewise-defined functions by graphing each function and restricting the domain. It covers graphing horizontal lines, inequalities, step functions, and complex piecewise functions. The tutorial also explains how to evaluate piecewise functions for specific x values, understand their domain and range, and address common misunderstandings. Additionally, it demonstrates how to express the absolute value function as a piecewise function.
