Answer:

See a solution process below:

Explanation:

This equation states for each and every value of #x# (the input), #y# is equal to #9#.

There are no restrictions on the input which is also the Domain. Therefore the Domain is the set of all Real Numbers or: #{RR}#

The output, for each and every input, is always #-9#

Therefore the Range is: #{-9}#
