I will assume that you meant $\"f%28x%29+=+ax%5E2+%2B+bx+%2B+c+\"$ . 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. \n" ); document.write( "
