The domain is all real numbers.

Explanation:

The domain of a function is the set of all numbers that you can plug into the function without ending up with an undefined computation like dividing by zero.

For example, the domain of #f(x)=1/x# is all real numbers except 0, because if you plug 0 into the function, you end up dividing by 0.

For the function provided in the question, there is nothing restricting the domain. All real numbers work.
