Further Modelling with Functions

How do I solve modelling problems?

  • There will be no one-size-fits-all step-by-step guide to solving modelling questions
  • A combination of skills and problem-solving skills will be needed

Assumptions, criticisms and refinements in modelling

  • Modelling is a large part of A level mathematics
  • Assumptions and refinements to models often need to be considered
  • Real-life general knowledge and common sense can really help in mathematical modelling

Examiner Tip

Read – and re-read – the question carefully. Try to “get involved” in the context of the question – however boring it may be!

    • Imagine what happens to a stone as you throw it from a cliff
    • What would it be like to manage a toy factory?

Draw a diagram – sketch a graph of the function being used as the model.

If you are completely stuck try “doing something” with the maths. For example, if there’s a quadratic function – sketch it, factorise it, solve it. Or if there’s a polynomial – use factor theorem and algebraic division to factorise it.
