Find the domain and range of the real function
`f(x) = sqrt(9 -x^(2))`

Explanation

To find the domain and range of the function \( f(x) = \sqrt{9 - x^2} \), we will follow these steps:

### Step 1: Determine the Domain
The expression under the square root must be non-negative for the function to be defined. Therefore, we need to solve the inequality:

\[ 9 - x^2 \geq 0 \]
