See below.

First we need to find the derivative of #f(x)=log(x)#

#d/dx(log(x))=1/x#

as #x->0^-color(white)(88888)# ,#1/x->-oo#

as #x->0^+color(white)(888)# , #1/x->oo#

The y axis is a vertical asymptote.

as #x->oocolor(white)(88888)# ,#1/x->0#

as #x->-oocolor(white)(888)# ,#1/x->0#

The x axis is a horizontal asymptote.
