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
For short term remembering: It really works if you take notes in class. I also found making connections to things you've experienced helps too.
For long term remembering - I found reviewing what you've learned recently is extremely useful. You can usually do this once in a couple of days until you're sure you can remember it.
Hope this helps!
