Answer
domain of $f=(0,\infty)$
range of $f=(-\infty,\infty)$
asymptote of $ f:\quad x=0$
domain of $g=(0,\infty)$
range of $g=(-\infty,\infty)$
asymptote of $g:\quad x=0$
.
Work Step by Step
$f(x)=\ln x$
$g(x)=-\ln(2x)=-f(2x)$
The graph of g is obtained from the graph of f by
horizontally compressing it by factor 2,
then reflecting about the x-axis
domain of $f=(0,\infty)$
range of $f=(-\infty,\infty)$
asymptote of $ f:\quad x=0$
domain of $g=(0,\infty)$
range of $g=(-\infty,\infty)$
asymptote of $g:\quad x=0$
