D. The range of the function is all real numbers greater than or equal to 0.

Step-by-step explanation:

The graph of the function $y=\sqrt{-x}$ is shown in attached diagram.

1. The domain of the function is the set of all possible values for input (for x). Hence, the domain of this function is

$x\in (-\infty,0]$

2. The range of the function is the set of all possible values for output (for y), so the range of this function is

$y\in [0,\infty)$

As you can see, only option D is true - The range of the function is all real numbers greater than or equal to 0.
