Exam-Style Question on Inequalities
A mathematics exam-style question with a worked solution that can be revealed gradually
Question id: 432. This question is similar to one that appeared on a GCSE Higher paper in 2017. The use of a calculator is allowed.
The red line in the diagram below shows an inequality. If the variable is \(x\), which inequality best describes \(x\)?
(a) \(-9 \le x \le 4\)
(b) \(-9 \lt x \le 4\)
(c) \(-9 \le x \lt 4\)
(d) \(-9 \lt x \lt 4\)
(e) \(-4 \le x \le 9\)
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.
