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.
