Answer
The domain of $\ln x $ is $(0,+\infty)$. The range of $\ln x $ is $ (–\infty,+\infty)$.
Work Step by Step
The domain of $\ln x $ is $(0,+\infty)$ because the log function is not defined for negative values or zero. The range of $\ln x $ is $ (–\infty,+\infty)$ because the $y$ value can take on any number.
