Which statement is true about the function f(x)=-√-x
Harrizon [31]

Answer: D.The domain and range of the function are the same.


Step-by-step explanation: Given function f(x)=-√-x.

The given function is a square root function and we have minus sign in front of x inside square root.

A square root always defined for positive values or 0.

In order to get a positive number or 0 inside square root, let us solve the inequality:

-x\geq 0

On dividing both sides by -1, the inequality sign would get flip and we get

<h3>Domain: x \leq 0.</h3>

We can see that we have a negative sign in front of square root. So, the value of f(x) would be always a negative number or 0.

<h3>Therefore, range would also be :x \leq 0..</h3><h3>Therefore, correct option is D option.</h3>
