- the y-axis if f(x) = f(-x) for all
- the origin if f(x) = -f(-x) for all
If a graph is symmetric to the x-axis it is not the graph of a function:
For every x-value you have pairs of y-values such that
To your function:
a) Symmetry to the y-axis:
That means: No symmetry to the y-axis.
b) Symmetry to the origin:
That means: Symmetry to the origin.
