comment Finding asymptotes of exponential function and one-sided limit
@Mhenni Why are the first two terms of the taylor series expansion enough to find the asymptote? Certainly there are functions where the first two terms wouldn't suffice to give an accurate approximation.

comment What are the limits and asymptotes of $f(x)=x+\frac{1}{x}$?
@Garmen1778 I'm not sure if you were implying that there was a horizontal asymptote or not, but in case there's any ambiguity, there are no horizontal asymptotes.
