This animation introduces function notation, explaining what f(x) means and how it represents a rule that maps inputs to outputs. Using a clear worked example, it shows how to substitute values into a function, evaluate expressions like f(3), and interpret the result. The visual breakdown helps students see the connection between algebraic expressions and function machines, making it useful for GCSE and IGCSE learners building a foundation in algebra before tackling composite and inverse functions.
