The domain is all real numbers, or #RR#.

Explanation:

#f# is a polynomial, and, by definition, all polynomials have all real numbers as their domain.

Alternatively, we can say that for any real value of #x#, #f(x)# is well-defined, exists, and is a real number as well. Therefore, the domain of this function is all real numbers.
