MHB Vertical Lines of x=5 & x=0 in y=ln(x-5)/x

[Petrus]

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

Regards,

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