Domain of cube root function

The domain of the square root function f(x) = √x is the set of all non-negative real numbers. i.e., the square root function domain is [0, ∞). Note that it includes 0 as well in the domain. In general, the square root of a number can be either positive or negative. i.e., √25 = 5 or -5 as 5 2 = 25 and (-5) 2 = 25.
