I believe but I am not too sure.
F(x)=a(x-h)^2+k
vertex is (h,k)
f(x)=1(x-6)^2-31
f(x)=1(x-(6))^2+(-31)
h=6
k=-31
vertex=(6,-31)
Answer:

Step-by-step explanation:
If it is a direct variation function, then
.
can be found by choosing a point and doing
divided by
.
So we can find
by doing -6 divided by -8 or 9 divided by 12.
Both of these values are equal to 0.75 or 3/4 as a fraction.
So you can say any point in this relation will follow the equation:

Multiply both sides by
:
