Find the maximum and minimum values of the following functions.
`f(x)=x^(3)-2x^(2)+x+6`

Explanation

To find the maximum and minimum values of the function \( f(x) = x^3 - 2x^2 + x + 6 \), we will follow these steps:

### Step 1: Differentiate the function
We start by finding the first derivative of the function \( f(x) \).

\[ f'(x) = \frac{d}{dx}(x^3 - 2x^2 + x + 6) \]
