Teach IB Maths AI SL 2.2 with guided notes covering functions, domain and range, function notation, and inverse functions.

Students learn how to:

• Identify whether a relation is a function
• Use and interpret function notation
• Determine the domain and range of a function
• Find restrictions for square-root and rational functions
• Understand inverse functions and the notation f⁻¹(x)
• Recognise when a domain restriction is needed
• Interpret inverses as reflections in the line y = x

Clear explanations, worked examples, and structured practice help students build confidence with foundational function concepts. The notes are ideal for classroom teaching, revision, exam preparation, or independent study.
