WebThe Standard Form of a Parabola can be plotted with the following equation: f (x) = ax2+bx+c. The Vertex to plot a parabola Graph can be derived using x=-b/2a and y = f (-b/2a). The quadratic equation can be presented as f (x) = a (x-h)2 + k, where (h,k) is the vertex of the parabola, its vertex form . Latus Rectum of the parabola is a line ... WebGiven the focus (h,k) and the directrix y=mx+b, the equation for a parabola is (y - mx - b)^2 / (m^2 +1) = (x - h)^2 + (y - k)^2. Equivalently, you could put it in general form: x^2 + 2mxy + m^2 y^2 -2[h(m^2 - 1) +mb]x -2[k(m^2 + 1)^2 -b]y + (h^2 + k^2)(m^2 + 1) - b^2 = 0
