Well, y=x/(x-1).
SO, y(x-1)=x, or yx-y=x.
So, yx-x=y, or x(y-1)=y, so x=y/(y-1).
So, that means y is any real number except 1.
So, the range is any real number except 1.

The range would include all real numbers--including y=1. The domain would be all real numbers excluding x=1.

' you can write y= x/(x-1)
then
(x-1) y =x
xy -y =x
x(y-1) =y
x = y/(y-1),
so the range of y is the domain of x, which in this case is all reals except y=1

All real numbers except 1.
