Answer:

The domain and range are all real numbers #RR#

Explanation:

The domain is the subset of #RR# for which the function can be calculated. It is a polynomial, therefore the domain is not limited.

The range is also #RR#. The end behaviour can be a hint. If #x# goes to #-oo# #y# also goes to #-oo# and if #x# goes to #+oo# #y# also rises to #+oo#
