A mathematics exam-style question with a worked solution that can be revealed gradually
Question id: 328. This question is similar to one that appeared on a GCSE Higher paper in 2017. The use of a calculator is not allowed.
The graph of y = f(x) is drawn accurately on the grid.
(a) Write down the coordinates of the turning point of the graph.
(b) Write down estimates for the roots of f(x) = 0
(c) Use the graph to find an estimate for f(-5.5).
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.
