Question

How do you find the Vertical, Horizontal, and Oblique Asymptote given `(x^2-64)/(x-8)`?

Answer 1

It doesn't have any.

Explanation:

The numerator factorizes to `(x-8)(x+8)` so you can cancel the `x-8`, so you are left with `x+8`. This is a straight line with gradient `1`, which, arguably, is a degenerate case of an oblique asymptote.
