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?
*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..
i get 2y>-3y
as long as y>0 then we should be OK..
