A square root function is a function that contains a square root with the independent variable in the radicand. The parent function for the family of square root functions is f (x) = √ x . The domain of f is x ≥ 0, and the range of f is y ≥ 0
The value of the radicand in a square root function cannot be negative. So, the domain of a square root function includes x-values for which the radicand is greater than or equal to 0.
