Web d =.5 (b + k) can eb written as 2d = b + k. The standard form of parabola when it. Web use h, k, and p to find the endpoints of the latus rectum, (h ± 2p, k + p) plot the vertex, axis of symmetry, focus, directrix, and. Determine the horizontal or vertical axis of symmetry. Web steps to find vertex focus and directrix of the parabola step 1. Identify h, k, and a for the parabola in vertex form y = a ( x − h) 2 + k through comparison of the constants. So now, if you have a parabla in vertex form you can take a and d and find b and k, where b.
