Shared across all four courses, functions are introduced formally with students developing fluency in domain, range, function notation and graphical representation. Composite functions are formed and inverse functions found, with students understanding that inverses exist only for one-to-one functions and are reflected in the line y = x. In AA the treatment is more analytical; in AI HL the content extends to include domain restriction when finding inverses and the formal composition f ∘ f⁻¹ = x.
