Lesson Plan: Domain and Range of a Piecewise Function Mathematics

This lesson plan includes the objectives and prerequisites of the lesson teaching students how to find the domain and range of a piecewise-defined function.


Students will be able to

  • recall the definitions of the domain and the range of a piecewise function,
  • identify the domain and range of a piecewise function given graphically or algebraically or both.


Students should already be familiar with

  • the domain and range of nonpiecewise functions,
  • piecewise functions,
  • open and closed dots on a graph,
  • set notation,
  • evaluating piecewise functions.
