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/xf(x)=1x 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.
