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
We start by differentiating the function \( f(x) \):

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