Answer:

Both the domain and range are all real numbers.

Explanation:

Since the function is defined for all real #x#, we can conclude that the domain is just the real numbers, #D=RR#.

The values of the function go from #-oo# to #oo#, and the function is continuous, which means that values can be all real numbers, so the range is also all real numbers, #R=RR#
