The parabola opens to the right. the focus is given as f(p, 0) and directrix x = –p. the distance between the focus and point p is equal to the distance between the directrix and point p. continue to simplify the equation to solve for y2. fp = qp = startroot (x minus p) squared (y minus 0) squared endroot = startroot (x minus (negative p)) squared (y minus y) squared endroot y2 =
