    Sure thing ^_^ it's the same as the one I mentioned before :) \( y = a(x - h)^2 + k \)

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

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

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

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

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