## Exam-Style Question on Graphs## A mathematics exam-style question with a worked solution that can be revealed gradually |

Question id: 296. This question is similar to one that appeared on a GCSE Higher paper in 2017. The use of a calculator is allowed.

The diagram shows part of the graph \(y=x^2-3x+6\).

(a) By drawing a suitable straight line, use your graph to find estimates for the solutions of \(x^2 - 4x + 2 = 0\) to one decimal place.

(b) A is the point (2,4). Calculate an estimate for the gradient of the graph at the point A.

The worked solutions to these exam-style questions are only available to those who have a Transum Subscription. Subscribers can drag down the panel to reveal the solution line by line. This is a very helpful strategy for the student who does not know how to do the question but given a clue, a peep at the beginnings of a method, they may be able to make progress themselves. This could be a great resource for a teacher using a projector or for a parent helping their child work through the solution to this question. The worked solutions also contain screen shots (where needed) of the step by step calculator procedures. A subscription also opens up the answers to all of the other online exercises, puzzles and lesson starters on Transum Mathematics and provides an ad-free browsing experience. |
