I was reading your 2014 free trial exam paper 1 for Specialist Maths and noticed an error to the solution of question 1. In part a, the question asks to simplify f(x) which results in a potential removal of a restriction to the original domain. Then in part b and c, it is important that the original domain which is R+ should be used instead of R\{0}. So the solution to part b should be [2, inf) and the graph in part c should have the right branch only.

Thanks to Sam Hu for pointing out:

In the solution to question 3b, W(z) is supposed to be k(z+i) where k is a non-zero real number and was unfortunately missed out. To make k=1 so that the question is accessible, it would be necessary to add some information in the question such as ‘the leading coefficient of T(z) is 1’.
