If the equation of a parabola is y = 2x^2 + 3x + 1, which of followings does not intersect with the
parabola?

(A)y = 2x^2 + 3x + 4

(B) y = (x^2)/3 + 3x + 2

(C) y = 4x^2 + 3x - 1

(D)y = (x^2)/2 + 3x + 4

(E) y = x2 + 3x + 3

Along with your answer could you guys explain how the coefficients in front of x^2 and x affect the graph?

Thanks!!
