IB Math AA SL 2.6 - Quadratic Functions

This IB Maths AA SL Topic 2.6 – Quadratic Functions resource introduces students to the key forms of quadratic functions and develops confidence in interpreting, transforming, and sketching parabolas. It covers the standard form, factorised form, and vertex form of a quadratic, along with the graph of a parabola, the y-intercept, x-intercepts, axis of symmetry, and vertex. Students are also guided through completing the square to convert quadratics into vertex form and identify important features of the graph more efficiently.

The lesson also develops understanding of how each form of a quadratic reveals different information, helping students move fluently between algebraic expressions and graphical features. With clear explanations, worked examples, graph-sketching practice, common mistake reminders, and fully worked solutions, this resource helps SL students build strong understanding of quadratic functions in line with IB Mathematics AA expectations.
