Which one did you choose first? it’s either B or C, i’m leaning more towards B though :))
The answer is -52
First you must substitute the variables
Then you must simplify

Hello :
f(x) = <span>a(x-k)²+k....... the point vertex is (h , k )
in this exercice : h = -3 and k = -1 s0 f(x) = a(x+3)²-1
find : a
but f(0)=8
a(0+3)² -1 = 8
9a-1=8
9a =9
a=1
f(x) =(x+3)²-1 =x²+6x+9-1
f(x) = x²+6x+8 .... (</span><span>the quadratic function in standard form )</span>
The coefficient of determination is the first one. I'm pretty sure.
