Answer
Domain: $(0,\infty)$
Asymptotes: $x=0; y=0;$
Local extrema: $(2.72,0.69)$
Work Step by Step
We are given the function:
$$y=\dfrac{\ln x}{x}.$$
Graph the function.
The domain of the function is:
$$\text{domain}=(0,\infty).$$
The asymptotes are:
$$x=0\text{ and }y=0.$$
There is a local maximum:
$$(2.72,0.69).$$
