Graph, Domain and Range of the Basic Cube Root Function: f(x) = ∛x. The domain of function f defined by f(x) = ∛x is the set of all real numbers. The range of f is the set of all real numbers.
The cube root of a number is a special value that, when used in a multiplication three times, gives that number. Example: 3 × 3 × 3 = 27, so the cube root of 27 is 3. See: Square Root.
