The directrix of a parabola is the vertical line found by subtracting from the x-coordinate of the vertex if the parabola opens left or right. Let 2a be the distance between the directrix and the focus. When we multiply a function by a positive constant, we get a function whose graph is stretched or compressed vertically in relation to The graph below shows a function multiplied by constant factors 2 and 0. The same goes for all of the other distances from a point on the parabola to the focus and directrix ( l 2, l 3 etc.. ). Taken as known the focus (h, k) and the directrix y = mx+b, parabola equation is [y - mx – b]² / [m² +1] = (x - h)² + (y - k)² . The vertex of a parabola is the coordinate from which it takes the sharpest turn whereas y=a is the straight-line used to generate the curve. Since we have x=4.75 for the directrix, this tells us that the parabola's axis of symmetry runs parallel to the x-axis.
