You can flip them and the graph looks the same. An instructional video shows how to determine whether an equation contains a graph that has symmetry. Scholars learn how to calculate algebraically whether an equation has symmetry about the x-axis, the y-axis, and the origin. Learners see an example of each type of symmetry.
- Lead a discussion on whether a graph that is symmetrical about the x-axis is a function
- Use symmetry to lead into a lesson on even and odd functions
- Assumes the class is familiar with graphing equations
- This video is hosted on YouTube
- Provides a graphical and functional definition of symmetry
- Uses colors to highlight the axis or points of symmetry
