WebIf a > 0 (positive) then the parabola opens upward. If a < 0 (negative) then the parabola opens downward. Find the x-intercepts: Notice that the x-intercepts of any graph are points on the x-axis and therefore have y-coordinate 0. We can find these points by plugging 0 in for y and solving the resulting quadratic equation (0 = ax 2 + bx + c ...
