1. As you stated correctly the vertical asymptotes correspond to the zeros of the denominator.

2. To get the horizontal or slanted asymptotes transform the term of the function into a complete polynomial and a fraction: Code:

x^2 + 1
(x^4 + 1) ÷ (x^3 - x) = x + -----------
-(x^4 - x^2) x^3 - x
------------
x^2 + 1

The none-fractional part of the term is the term of the slanted asymptote. That means in your case the slanted asymptote has the equation:
