All 2 lessons in Functions and Mappings

  1. 1. What Is a Function? Notation, Domain, Co-domain and Range

    Write and evaluate a function in the notation f : x -> ..., name its domain, co-domain and range, use the vertical-line test to tell a function from a relation, and recognise that two different inputs may share one output.

  2. 2. Types of Mapping: One-to-One, Onto, Identity and Constant

    Classify a mapping as one-to-one or many-to-one, as onto or into, and recognise the identity and constant mappings, reading each property directly from an arrow diagram.
