Your parabola is described by this equation: f(x) = (x-2) (x-6) What relationship do you see between this function and its roots?
Answered by mathhelper
Perhaps that the roots, which are x = 2 and x = 6, happen to be where the parabola cuts the x-axis ?
Or it could be that the vertex would lie on a vertical line half way between
2 and 6 ?
