Use the discriminant to determine the relationship between the graph of each function and the xx-axis: (a) y=x2+x−2y = x^2 + x - 2 (b) y=x2−4x+1y = x^2 - 4x + 1 (c) y=−x2−3y = -x^2 - 3 (d) y=x2+7x−2y = x^2 + 7x - 2 (e) y=x2+8x+16y = x^2 + 8x + 16 (f) y=−2x2+3x+1y = -2x^2 + 3x + 1 (g) y=6x2+5x−4y = 6x^2 + 5x - 4 (h) y=−x2+x+6y = -x^2 + x + 6 (i) y=9x2+6x+1y = 9x^2 + 6x + 1
