A, because you if you try to divide 0 into 15 parts you get 0
we do 2x-1/y=w+2/2z
2x-1/y we multiple each side y
2x-1/y×y=2x-1
then w+2/2z
we said×2z×2z
then we got
w+2
later
2x-1=w+2=
then 1 become another side
which is 1+2=3
then
w=3-2x
I hope it's correct
F(x)=x^2-4x+7

What’s the question that you have
The answer is A. I plugged it into a TI-83 calculator. If you need to know how I did that I will be happy to help
