Reading and Consolidation
When you have completed your explorative and interactive learning, read and work through pages 1-26 in your coursebook, practising and consolidating your knowledge by completing all of the relevant exercises.
Areas covered:
- Mapping
- Definition of a function
- Composite functions
- Modulus functions
- Graphs of y = f(x) where f(x) is linear
- Inverse functions
- The graph of a function and its inverse
All answers to the coursebook exercises can be found in your digital version or in General Resources on Canvas.
Quiz
Now that you have completed all of the topics, it is time to check your understanding by taking the multiple-choice quiz. You must pass this quiz before moving on to the assignment and the next module. Remember that you can do the quiz as many times as you want to practise and learn. Use it as an opportunity to test yourself!
