Candidates should not assume that examiners will read 2(x – 1) – x + 1 as 2(x – 1) – (x + 1). Part (b) was one of the most testing parts of the paper and very few obtained the fully correct answer 0 < f(x) < . Many had no idea at all how to find the range and many defaulted to the answer “all real numbers”.
