Answer:
(B). F(X)=2x^2+2x-4
Step-by-step explanation:
-4 means it passes through -4 at the y axis
B and D have -4
graph passes thru x axis at -2 and 1
if you enter x = -2 or 1 in the formula
(B). F(X)=2x^2+2x-4
you get 0
it's not D because when you enter -2 or 1 for x
you don't get 0
you get 8 and -4
x < -9 or x > 7
x + 1 < -8
x < -9
x + 1 > 8
x > 7
... when the inequality sign is facing the x, x is GREATER and it resembles an OR statement. I personally like to think of it as: greater than (greatOR than) = or statement; less than (less thAND) = and statement.
