Is the statement true or false: numbers in the range of a radical function will always be nonnegative?

Answer 1

False.

It should be noted that the radical function includes cube roots, fifth roots, and so on; when the radicand is negative, these odd roots accept negative values as real-valued functions.

For example, the real cube root of #-1# is #-1#.
