Find the asymptotes of $\frac {1}{f}$

My answer: x=2 and y= -1/3 (x -> +oo )

but I can't get anything when x -> -oo

Hi JoanF,

yes, there are two asymptotes.

As $x\rightarrow-\infty,\ y=\frac{1}{f}\rightarrow\ \infty$

The graph is not asymptotic there,
to be asymptotic, the graph approaches a straight line.
