Answer:

Since the #ln# function is only defined for positive arguments, the domain is #x>3# with no upper limit, or in other words #3 < x < oo#.

Explanation:

The #ln# function can reach any value from #-oo->+oo# (even if it rises very slowly), which will not change is we add #2#. So this is the range .
graph{ln(x-3)+2 [-37.34, 55.15, -23.9, 22.35]}
