Question

Which functions have graphs that are symmetrical with respect to the y-axis?

Answer 1

Answer:

Even powered functions that do not move left or right

($x^{2}$, $x^{4}$, $x^{6}$... )

Step-by-step explanation:

$x^{2}$, $x^{4}$, $x^{6}$... would all be symmetrical to the y-axis.

A horizontal shift in the graph like $(x-2)^{2}$ would not be symmetrical to the y-axis.
