Parabola using focus and directrix

Web1 answer. The vertex of the parabola is located halfway between the focus and the directrix, which is at (−7,5). The axis of symmetry of the parabola is a horizontal line passing through the vertex. Since the directrix is below the vertex, the parabola opens upwards.
