Homework Statement
Find the oblique asymptote and sketch the graph
Homework Equations
f(x)=x^3+3x^2-x-5/x^2-1
The Attempt at a Solution
My question is that shouldn't 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?
