Domain of cube root function.
A cubic function is a polynomial function of degree 3 and is of the form f (x) = ax 3 + bx 2 + cx + d, where a, b, c, and d are real numbers and a ≠ 0. The basic cubic function (which is also known as the parent cube function) is f (x) = x 3. Since a cubic function involves an odd degree polynomial, it has at least one real root.
