The vertex of a parabola is at (12,-4), and its axis of symmetry is vertical. One of the x-intercepts is at (18,0). What is the x-coordinate of the other x-intercept?

The vertical axis of symmetry is  x = -12    the x intercepts are on either side of this at the same distance

   the second intercept will be at x = 6                      (   6,0   )
