Answer:

0 to ∞

Explanation:

range means y

make equation equal to 0

The range of the square root of a number is all non-negative real numbers, since the square root of a negative number is not a real number. Therefore, the range of the square root of {-x-2} is **[0,∞)**.

Another way to find the range is to set the radicand, {-x-2}, greater than or equal to zero and solve for x.

```

-x-2 >= 0

x <= -2

```

This means that the domain of the square root function is all real numbers less than or equal to -2. Since the range of the square root function is all non-negative real numbers, the range of the square root of {-x-2} is also **[0,∞)**.
