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. The distance from the vertex to the focus is equal to the distance from the ... WebThe keywords for parabolas are the vertex, the focus, the directrix, and the axis of symmetry. To form a parabola according to ancient Greek definitions, you would start with a straight line and a point off to one side; the line is called the directrix; the point is called the focus. The parabola is the curve formed from all the points (x, y) ...
