Answer
The domain is $(0, \infty)$
The range is $(-\infty,0]$
The x-intercept is (1,0).
There are no y-intercepts.
Work Step by Step
The domain is a horizontal span from the function's smallest value of x to the function's largest value of x. If there is a discontinuity, the domain must show where the discontinuity happens.
The range is a vertical span from the function's smallest value of f(x) to the function's largest value of f(x). If there is a discontinuity, the range must show where the discontinuity happens.
The x-intercepts are all points of a graph when f(x)=0 while the y-intercepts are all points of a graph when x=0. In this case, there is only the x-intercept:
$0=-ln(x)$
$0=ln(x)$
$e^0=x$
$x=1$
