Preparing for your IB Math AA HL exams? In this quick and clear tutorial, we walk through the step-by-step solution for Question 1 from the May 2025 TZ1 Paper 1.

This 5-mark calculus question tests your ability to find the local minimum of a cubic function. In this video, we cover:
✅ How to correctly differentiate the function to find f'(x).
✅ Setting the derivative to zero to identify critical points (local extrema).
✅ Selecting the correct positive x-value (p must be positive) as specified by the question.
✅ Substituting the x-value back into the original function to calculate the exact y-coordinate (q).

This is a perfect, concise review for applying differential calculus in a non-calculator (Paper 1) setting!
