Year 12 Retrieval: Composite Functions and Domains
Investigating the formation of composite functions and determining their valid domains and ranges.
Key Questions
- Evaluate how domain restrictions on composite functions affect the validity of calculus operations such as differentiation and integration encountered in Year 13.
- Analyse how compositions involving inverse trigonometric or logarithmic functions introduce domain constraints that must be managed when solving differential equations.
- Synthesise a composite function model for a real-world scenario, specifying its maximal domain and linking it to a related rates-of-change problem.
