A) y = x2 − 9
y = x2 + 2x + 9
B) y = x2
y = x2 + 2x + 9
C) y = x2 + 2x
y = x2 + 9
D) y = x2
y = 2x + 9

Best ResponseYou've already chosen the best response.1The way you can check, is by setting each equation in the system equal to each other and see if you get the above equation Example: The first one y = x2 − 9 y = x2 + 2x + 9 Set them equal x^29=x^2+2x+9 This is not what we started with, so it is not the answer.
