y \in RR

Explanation:

The range of f(x) = ln(x) is y \in RR.

The transformations done to get 3-ln(x+2) are to shift the graph 2 units left, 3 units up, and then reflect it over the x-axis. Of those, both the shift up and the reflection could change the range, but not if the range is already all real numbers, so the range is still y \in RR.
