There are three types of symmetry:

1. X-Axis Symmetry

2. Y-Axis Symmetry

3. Origin Symmetry

If exists on the graph, then the graph is symmetric about the:

1. X-Axis if exists on the graph

2. Y-Axis if exists on the graph

3. Origin if exists on the graph

Check if the graph is symmetric about the x-axis by plugging in for .

Apply the product rule to .

Raise to the power of .

Multiply by .

Since the equation is identical to the original equation, it is symmetric to the x-axis.

Symmetric with respect to the x-axis

Check if the graph is symmetric about the y-axis by plugging in for .

Apply the product rule to .

Raise to the power of .

Multiply by .

Since the equation is identical to the original equation, it is symmetric to the y-axis.

Symmetric with respect to the y-axis
