Lesson Plan: Symmetry of Graphs and Functions
This lesson plan includes the objectives and prerequisites of the lesson teaching students how to determine the symmetry of functions about axes and points.
Objectives
Students will be able to
- identify functions whose graphs have rotational or reflectional symmetry,
- find the axes and points of symmetry in these cases, both graphically and algebraically.
Prerequisites
Students should already be familiar with
- summation notation.
