x and y are consecutive positive integers and: x>y, x^2-1> y^2-4y+x-1

Which of the following represents all the possible values of y?
y>=0
y>0
y>1
y>7
y>8

*May have been asked before but couldn't find it on the board. Not sure why A is not right. When I plugged in numbers that seems to be fine.

OK so we are told that x=y+1..

(y+1)^2=y^2+2y>y^2-3y
i get 2y>-3y

as long as y>0 then we should be OK..

I'm realizing I have issues reading problems correctly considering I completely missed the whole "positive" word in the question! Thanks for your time.
