I am suppose to find the end behavior of

[(u-1)(u-2)^2(u-3)^3)/((u-1)^3(u-2)^2(u-3))

I looked at my calculator and what I can determine is

as x approaches negative infinity f(x) approaches 1 and as

x approaches positive infinity f(x) approaches 1

am I doing this right, or is there something I am missing??

Please Help

Thanks
