Functions
IB Topic 2, complete: straight lines, the function concept, graphs and their key features, composite and inverse functions, quadratics from every angle, the discriminant, rational functions, exponential and logarithmic graphs, equation-solving strategy, and graph transformations — SL 2.1 to 2.11, taught to markscheme standard.
Builds on
Topic 1's exponent and logarithm machinery (SL 1.5, 1.7) powers the exponential lessons; everything else needs only solid GCSE/MYP algebra.
