- All real numbers greater than or equal to 0.
Explanation:
Domain of a function--
The domain of a function is the set of all the possible values of x for which the function is defined.
Range of a function--
The range of the function is the set of values which are attained by a function in it's domain.
We are given a function f(x) as:

We know that the domain of the function is:

Hence, if

then,

i.e.

Hence, the range of the function is:
f(x)≥0
i.e. all the real numbers greater than or equal to zero.
