Jordan pose la question :
'Look at these expressions'

n-2, 2n, n(squared), n over 2, and 2 over n (sorry I can't type the expressions out)

A) Which expression gives the greatest value when n is between 1 and 2?
B) Which expression gives the greatest value when n is between 0 and 1?
c) Which expression gives the greatest value when n is negative?

As you can see, this IS ONE question split in to three parts lol!

Can you tell me how I go about tackling this question? I lost marks on the test because of not understanding the question.
