In this lesson, we solve part (b) of Question #02 from the AIOU 1429 Business Mathematics past paper (Spring 2025). You will learn how to investigate maxima and minima of a cubic function using:

  • Finding stationary points via the first derivative.

  • Applying the second derivative test to determine whether each stationary point is a local maximum or a local minimum.

This skill is essential for optimization problems in business and economics.
