## Babyslapmafro 3 years ago True or false? L'Hopital's rule does not apply to the following function (click to see).

1. Babyslapmafro

$\lim_{x \rightarrow -\infty}\frac{ lnx}{ x}$

2. Babyslapmafro

lnx is undefined if x<0 right, so my guess is that the statement is true...

3. KingGeorge

I think you're correct. Since the natural log is undefined for negative numbers, the limit as x goes to -infinity of ln(x) is undefined, so you can't use L'hopitals.

ok thank you

5. KingGeorge

You're welcome.
