Easily factorable left quadratic member, %28x-2%29%28x%2B4%29=0

Zeros at 2 and -4, and the vertex is in the exact middle of these; but if you want to just graph the equation, this will be just the two points on a single number line. Notice, quadratic expression equaling 0.

(if in two dimensions, vertex would occur at x=-1).
