How to find vertex, focus, directrix of a parabola
How To Find Focus And Directrix From Vertex Form. Web d =.5 (b + k) can eb written as 2d = b + k. We are looking here at two.
So now, if you have a parabla in vertex form you can take a and d and find b and k, where b. Web d =.5 (b + k) can eb written as 2d = b + k. We know that the maximum (or minimum) y value of a parabola will occur at its vertex. We are looking here at two.
