    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

    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.
