Answer
The domain of the function is $(0, +\infty)$.
Work Step by Step
RECALL:
The domain is the set of all the x-values of the graph.
Notice that the function's graph covers all the x-values to the right of zero.
This means that the x-values covered by the function are the ones greater than 0
Thus, the domain of the function is:
$(0, +\infty)$
