# Math Help - how to create x-axis symmetry

1. ## how to create x-axis symmetry

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

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

3. ## Thank you

Thank you very much.
