Answer:
C) The range of the function is all real numbers less than or equal to 0.
Step-by-step explanation:
Given function:
[tex]f(x)=-\sqrt{x}[/tex]
Domain
The domain of a function is the set of all possible input values (x-values).
As the square root of a negative number cannot be taken, x ≥ 0.
Therefore, the domain of the function is all real numbers greater than or equal to 0.
Range
The range of a function is the set of all possible output values (y-values).
As the domain is x ≥ 0, the range of the function is all real numbers less than or equal to 0.
