## Algebra and Trigonometry 10th Edition

Vertical asymptotes: $x=±1$ There is no horizontal asymptote.
For the vertical asymptote, the denominator must be equal to $0$: $x^2-1=0$ $x^2=1$ $x=±1$ The degree of the numerator is greater than the degree of the denominator. So, there is no horizontal asymptote.
