Find all possible values of
`sqrt(|x|-2)`
.

Explanation

To find all possible values of the function \( f(x) = \sqrt{|x| - 2} \), we need to determine the domain of the function and analyze its behavior.

### Step 1: Determine the domain of the function
The expression inside the square root, \( |x| - 2 \), must be greater than or equal to 0 for the square root to be defined. Therefore, we set up the inequality:

\[ |x| - 2 \geq 0 \]
