If the focus of a parabola is 0 -3

WebThe straight line passing through the focus and perpendicular to the directrix is called the Axis of the Parabola. The parabola is a symmetrical about its axis (i.e. line). It means if lies on parabola. then also lies on other sides of the axis. WebWe also notice that when x is 0, the distance from P to the focus equals the distance from the vertex to the directrix. So the focus and directrix are equidistant from the vertex. A parabola is a locus of points equidistant (the same distance) from a line called the directrix and point called the focus. © Eugene Brennan Definition of a Parabola
