Find the value of x for which the function `(x^(3) - 3x + 4) `is maximum or minimum.

Explanation

To find the value of \( x \) for which the function \( f(x) = x^3 - 3x + 4 \) is maximum or minimum, we will follow these steps:

### Step 1: Find the first derivative of the function
To find the critical points, we first need to compute the first derivative of the function \( f(x) \).

\[ f'(x) = \frac{d}{dx}(x^3 - 3x + 4) = 3x^2 - 3 \]
