Answer:

  (c)  The range of the function is all real numbers less than or equal to 0

Step-by-step explanation:

You want the true statement describing the domain or range of f(x) = -√x.

Domain

The domain of the function is the set of values x for which the function is defined. The square root is only defined for non-negative arguments:

  x ≥ 0 . . . . . . not an answer choice

Range

The range is of the function is the set of values f(x) that the function can produce. The square root function can produce any non-negative value, so the opposite of the square root function will produce any non-positive value:

  f(x) ≤ 0 . . . . . the range is real numbers less than or equal to zero
