Vertical line

Hello MHB,
I did find a problem in internet
$$\displaystyle y=\frac{ln(x-5)}{x}$$
they say there is a vertical line at $$\displaystyle x=5$$ but should there not also be a vertical line at $$\displaystyle x=0$$?

Regards,
$$\displaystyle |\pi\rangle$$

$$\displaystyle \ln(x-5)$$ is undefined at $x=0$ actually the function cannot get closer to this line.
