The set of points in the red oval X is the domain of f. Graph of the real-valued square root function, f ( x) = √x, whose domain consists of all nonnegative real numbers. In mathematics, the domain of a function is the set of inputs accepted by the function. It is sometimes denoted by or , where f is the function.
