These are the Transum resources related to the statement: "Pupils should be taught to where appropriate, interpret simple expressions as functions with inputs and outputs; {interpret the reverse process as the ‘inverse function’; interpret the succession of 2 functions as a ‘composite function’}".

Here are some specific activities, investigations or visual aids we have picked out. Click anywhere in the grey area to access the resource.

- Brainbox A puzzle requiring the arrangement of numbers on the function machines to link the given input numbers to the correct output.
- Functions An online exercise on function notation, inverse functions and composite functions.

Here are some exam-style questions on this statement:

- "
*\(f(x) = \frac{2x}{5} + 7\) and \(g(x) = 10x^2 - 15\) for all values of \(x\).*" ... more - "
*The function \(f\) is described by the following formula:*" ... more - "
*(a) A function is represented by the following function machine.*" ... more - "
*If \(f(x)=5-4x\) and \(g(x)=4^{-x}\) then:*" ... more - "
*Here is a function machine that produces two outputs, A and B.*" ... more - "
*The functions f and g are defined as follows:*" ... more
