The parabola hits (-2,1) and (0,-1).
As you can see from the pictures, we can immediately cross out options B and D, since both parabola open upwards.
From the pictures, we can see that the answer is C, since only that parabola opens downwards and hits the points (-2,1) and (0,-1).

1.) (x - 4)(x + 1) = 0
x^2 + x - 4x - 4 = 0
y = x^2 - 3x - 4
2.) (x - 2)(x - 6) = 0
x^2 - 6x - 2x + 12 = 0
x^2 - 8x + 12 = 0
since the function has a maximum point the leading coefficient is negative.
Therefore, required equation is y = -3x^2 + 24x - 36
3.) a(x + 3)^2 = ax^2 + 6ax + 9a
since the y intercept is at y = 18 => 9a = 18 => a = 2
Therefore, required function is y = 2x^2 + 12x + 18
