If we consider only parabolas that open upwards or downwards, then the directrix will be a horizontal line of the form y = c y = c . Let (a, b) ( a, b) be the focus and let y = c y = c be the directrix. Let (x0,y0) ( x 0, y 0) be any point on the parabola.This equation uses x^2=4py to find the focus, where (0,p) is the focus. Since x^2 equals -13y (after subtracting 13y from both sides of the equation), this means that -13y=4py -> -13=4p -> p=-13/4. So we know the focus is (0,-13/4).The equations of parabolas with vertex \((0,0)\) are \(y^2=4px\) when the x-axis is the axis of symmetry and \(x^2=4py\) when the y-axis is the axis of symmetry.

Thus, we can derive the equations of the parabolas as: y 2 = 4ax. y 2 = -4ax. x 2 = 4ay. x 2 = -4ay. These four equations are called standard equations of parabolas. It is important to note that the standard equations of parabolas focus on one of the coordinate axes, the vertex at the origin.x2 = 4py x 2 = 4 p y. 1) As the parabola opens downward, so the vertex is the highest point and the directrix line will be above the vertex. As the vertex is at (0,0) so the directrix will cross through the positive part of the y-axis.
