Question

The function f(x) = -sqrt x is shown on the graph. Which statement is correct?

Answer 1

Answer: C.

equal to 0

Explanation:

Answer 2

correct choice is C

Explanation:

Consider the parent function
`y=√(x).` The domain of this function is
`x\ge 0` (all real numbers greater or equal to 0), the range of this function is
`y\ge 0` (all real numbers greater or equal to 0).

The graph of the function
`y=-√(x)` can be obtained from the graph of the function
`y=√(x)` by reflection across the x-axis. This means that the range of the function is refleted too and becomes
`y\le 0` (all real numbers less or equal to 0).

Therefore, correct choice is C
