Note : The x value of the vertex of a parabola always lies exactly in the middle between the zeros (generally, since some parabolics do not have zeros: in the middle between the two x values with the same function value)
And the middle between two x values is:
The x-coordinate of the vertex is located in the middle between the zeros.
