Can someone give me the formula on how to do this?

Answer 3

Sure thing ^_^

it's the same as the one I mentioned before :)

\( y = a(x - h)^2 + k \)

Answer 4

where \( (h, k) \) is the vertex

Answer 5

then you can *temporarily* plug in the "given point"
as (x, y) to find "a" :)

Answer 6

if you get stuck on some part of it, just ask ^_^

Answer 7

Aaah I see, thank you once again! (:

Answer 8

Ok I plugged in the equation, just checking if I did it right but would the answer be D?

Answer 9

hmmm
make sure when you first plugged in the vertex, you got:
\( y= a(x+4)^2+3\)
^ plus 4 ?

Answer 10

but no, I don't think it's D
try again? :)

Answer 11

Ok got it now, so it would be B?

Answer 12

yeah B is right ^_^"
