D. All real numbers
Step-by-step explanation:
The range of a function is all of the possible x-values (which is easiest to understand if you can view a graph), and the domain of a function is all possible y-values.
So, you could put any x-value into this function (and it would have a corresponding y-value)
The domain [y] is limited, but the range [x] is best described as all real numbers
(if it's hard to remember which is which, d comes before r alphabetically, and x comes before y alphabetically)
