Hi

In application of limits (Asymptotes)

$\displaystyle f(x)=x+1/x$ is the function

Hoxizontal Asymptotes

solution

$\displaystyle lim x-infinity f(x) = lim x-infinity [ x + 1/x ] = infinity $

but Vertical Asymptotes why? $\displaystyle limx-0$

$\displaystyle lim x-0 f(x) = lim x-0 [ x + 1/x ] = infinity $

thanks a lot
