y = 6x2 + 4 ; y = x2; y = -0.5x2; y = 0.1x2 + 3; y = -9x2
y = -9x2; y = 6x2 + 4; y = x2; y = -0.5x2; y = 0.1x2 + 3
y = -9x2; y = -0.5x2; y = 0.1x2 + 3; y = x2; y = 6x2 + 4
y = x2; y = 0.1x2 + 3; y = -0.5x2; y = 6x2 + 4; y = -9x2;
y = 0.1x2 + 3; y = -0.5x2; y = x2; y = 6x2 + 4; y = -9x2;
y = 0.1x2 + 3; y = -0.5x2; y = x2; y = -9x2; y = 6x2 + 4
