Functions is where 0606’s notation turns strict, and it rewards close feedback more than location, which is good news for Cheras students who have often had to travel into KL to find a genuine 0606 specialist. Functions, composite and inverse, domain and range, and modulus, runs through the whole paper, and the exam is unforgiving about how the answer is written.
Where Cheras students lose functions marks
The lost marks are notation and order, not understanding:
- Composite functions: means first, then ; reversing it is the classic slip.
- Inverse functions: the domain of the inverse is the mark most often forgotten.
- Range and one-one: why a domain must be restricted before a function can be inverted.
These are habits, replaced fastest when a specialist marks every line rather than just the answer.
Cheras logistics, taught online
