Look at the examples in question 5 on the previous page to see how to write them. You call the input (top number) x, and then write what has happened to x as your rule. eg in Q5 on page 25 diagram C, the output numbers are all 1 less than the input numbers so the mapping is x -> x-1 Does that help? Hi Grace,

The selling price is 4 times the purchase (buying) price if it is milk, and 1.5 times the purchase price if it's yoghurt. The info given is the selling price and you have to work backwards to find the purchase price. JT Hi Juliette,

Think about what each expression means, eg what does 2n actually mean? What does n squared actually mean? Don't guess. Work out if what they say is true or not. Hi Elise,
