Ugh more review sheets!

Define: f0,1) -> R by f(x) = ($\displaystyle x^3$-$\displaystyle x^2$+x-1)/(x-1). Prove that f has a limit at 1.

It says that we shouldn't have to use $\displaystyle epsilon$ and $\displaystyle delta$ so that blew my whole idea of showing it was <$\displaystyle epsilon$. So would I got about it by dividing everything by $\displaystyle x^3$ and so on? or do I need to show an actual proof?

thanks
