(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Find the oblique asymptote and sketch the graph

2. Relevant equations

f(x)=x^3+3x^2-x-5/x^2-1

3. The attempt at a solution

My question is that shouldnt there be a hole in the graph when x=-1 or 1? The denominator would end up being zero.

When should i be using an hole or when do i know it is an asymptote?
