# Algebra Examples

Determine if the function is odd, even, or neither in order to find the symmetry.

1. If odd, the function is symmetric about the origin.

2. If even, the function is symmetric about the y-axis.

Find by substituting for all occurrence of in .

Remove parentheses.

Check if .

Since , the function is not even.

The function is not even

The function is not even

Multiply by .

Since , the function is odd.

The function is odd

The function is odd

Since the function is odd, it is symmetric about the origin.

Origin Symmetry

Since the function is not even, it is not symmetric about the y-axis.

No y-axis symmetry
