Question 1031236: Which quadrants contain the graph of any function f(x) = ax^2 + bc + c if a < 0 and the discriminant D < 0? Answer by robertb(5830) (Show Source):
You can put this solution on YOUR website! I will assume that you meant . The discriminant being negative implies that the quadratic function will have no real roots, hence no x-intercepts. a > 0 implies that the parabola opens upward. Therefore quadrants I and II will contain the graph of the function, or the parabola.
