To create y-axis symmetry, we need to use the absolute value of the input.

What do you need to do to give the graph x-axis symmetry?

Thank you very much

You simply take the absolute value of y. For example, $\displaystyle y = 2x + 3$ becomes $\displaystyle |y| = 2x + 3$ and $\displaystyle x = y^2$ already has symmetry across the x-axis, since $\displaystyle |y|^2 = y^2$.
