Web1 Answer. Plug in ( x, y) = ( 18, 13.6) to get 13.6 = a ( 18 − 12) 2 + 16 and then solve for a. You can do this because you know the point ( 18, 13.6) is on the parabola, so it must satisfy the equation. thanks. it seems so obvious, but i didn't think of it - probably because it's a quadratic formula and we started it only today.
