How to use These Past Paper Questions

For our example we will take the question 9-F from 2014 paper 1 (shown below). This falls under the derivatives topic. The papers often mix topics into parts of a question. In order to answer part F, you need to take the derivative of \(f(x)\).

But the definition of \(f(x)\) comes from the question of part D. So the question of part D is included so that you know what \(f(x)\) refers to. Notice, no answer box is included because you are not meant to answer it here, since part D is not relevant to the topic of derivatives.

Now you know \(f(x) = Ae^{kt}\), but what is \(A\) and \(k\) and \(t\)?

You had to figure out \(A\) and \(k\) in parts A and B, but these parts are not relevant to derivatives. So these questions and their answers are included, as though you have answered them already.

\(t\) refers to time, which you might have guessed, but the context of the overall question is included at the top just in case.

In general, each question you see will have a title telling you what part you are to answer. There is an example of this below. Another clue is the answer box. If the image included an answer box for one of the question parts, you are meant to answer that part.
