Find all points of local maxima and local minima of the function f given by`f(x)=x^3-3x+3`.

Explanation

To find the local maxima and minima of the function \( f(x) = x^3 - 3x + 3 \), we will follow these steps:

### Step 1: Find the first derivative of the function
We start by differentiating the function \( f(x) \) with respect to \( x \).

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