In this lesson, we unpack a full Cubic Functions question — step by step — perfect for Matric revision and exam preparation! 🧮
📘 Questions Covered:
9.1 f(x) = x³ - 6x² + 9x - 4 = (x - 4)(x - k)² → Show that k = 1
9.2 Calculate the turning points of f
9.3 Describe the concavity at x = -3
9.4 Sketch f showing turning points and intercepts
9.5 Find the maximum vertical distance between f and h for 1 is less than x and x is less than 3, where h(x) = -2f'(x)
💡 Learn how to:


Factorise and simplify cubic functions


Find turning points using derivatives
