To find the points of local maximum and minimum for the function \( f(x) = x^3 - 3x^2 - 9x \), we will follow these steps: ### Step 1: Find the first derivative of the function The first derivative \( f'(x) \) is calculated as follows: \[ f'(x) = \frac{d}{dx}(x^3 - 3x^2 - 9x) = 3x^2 - 6x - 9 \] ...
