Mathematics Advanced Year 11 - Module 1 - Lesson 8
Working with Functions — Synthesis
1. Key Ideas
Real problems do not arrive labelled "find the inverse" or "evaluate the composite." They demand that you choose the right tool, combine several ideas, and work step by step. This lesson brings together everything you have learned about functions, notation, domain, inverses, and composites into integrated, exam-style problems.
- How to combine evaluation, domain, inverse, and composite skills
- Why breaking a complex problem into smaller steps is essential
2. Success Criteria
By the end, you should be able to:
- How to combine evaluation, domain, inverse, and composite skills
- The connections between algebraic and graphical representations
- Common exam question structures that mix multiple concepts
3. Key Terms
