Answer 1

Do you have any idea?

Have you graphed it? :P

Answer 2

Yes, I have graphed it. I believe the answer is B. or D. I am a little confused about it actually.

Answer 3

Hint:

\(\sf ax^2+bx+c\)

If \(\sf a>0\) then it opens upwards
If \(\sf a<0\) then it opens downwards

Answer 4

What does your graph look like? o.O

Make sure you graphed it correctly.

Answer 5

Oh, then the answer is A. And I meant to say A. or B. not D. XD
