IB Math AA SL 2.3 - Graphing Functions

This IB Math AA SL 2.3 – Graphing Functions resource develops students’ ability to represent functions graphically from equations, tables, and contextual information. The lesson links ordered pairs and tables of values directly to plotted graphs, reinforcing how algebraic rules translate into visual behaviour, while also clarifying the IB distinction between a precise drawn graph and an approximate sketch .

Students learn to extract key graphical features such as intercepts, turning points, symmetry, and asymptotes, and apply these when graphing from context or screen-based information. The resource also introduces graphing sums and differences of functions, emphasizing that function operations affect outputs while standard graphing principles remain the same .

With modelling examples, technology integration, and exam-style tasks requiring correct scale, labelled axes, and identified features, this lesson builds strong SL-level confidence in moving between algebraic expressions and their graphical representations in IB Mathematics.
