Find the maximum or minimum values of the function.
`y=9-(x-3)^(2)`

Explanation

To find the maximum or minimum values of the function \( y = 9 - (x - 3)^2 \), we can follow these steps:

### Step 1: Identify the function
The given function is:
\[ y = 9 - (x - 3)^2 \]

### Step 2: Differentiate the function
To find the critical points, we need to differentiate the function with respect to \( x \):
