Sketch and Factorize Cubic Functions

The video tutorial explains the general shape and characteristics of cubic functions, including positive and negative trends, turning points, and roots. It covers how to identify and factorize cubic functions with different root scenarios, such as three roots, two roots with a repeated root, and a single root with a point of inflection. The tutorial also discusses using differentiation to find turning points and intercepts, and provides a step-by-step guide to sketching cubic functions using the factor theorem and algebraic division.
