Recognise when different inputs give the same output
For \(f(x)=-x^{2}+6x\), calculate both outputs and the output change from \(2\) to \(4\).
Worked practice: function notation
Evaluate the function at the requested inputs and compare the change in output.
Write a full answer
Now write the response in full, in your own words — this is what the exam asks for. The AI marks it on the same moves you built above (focus, evidence, technique, judgement) and gives feedback on reasoning, evidence, and expression.
