"WebTo find the vertex of a quadratic function in factored form, we take the average of the zeros. So, for the quadratic in factored form. f (x) = a (x – r) (x – s) we calculate c = (r + s) / 2 to find the x-coordinate of the vertex. Then, we plug in x = c into the function f (x) to find the y-coordinate of the vertex (we’ll call it d). " - Finding zeros from vertex form
