Plots of real-valued quadratic function ax2 + bx + c, varying each coefficient separately.

For the quadratic function:
f (x) = x2 - x - 2 = (x + 1)(x - 2) of a real variable x, the x-coordinates of the points where the graph intersects the x-axis, x = -1 and x = 2, are the roots of the quadratic equation: x2 - x - 2 = 0.
