Cube Root Function

A radical function in which the index of the radical is 3 is also called a cube root function. The parent function of the cube root function family is f(x) = sqrt(x).

It is worth noting that the cube root is defined for all real numbers. This means that the domain of f(x)=sqrt(x) is the set of all real numbers. Furthermore, any real number can be written as the cube root of a number. This leads to the range of this function being all real numbers. f(x)=sqrt(x) ↙ ↘ cc Domain & Range all real numbers & all real numbers
