Hi all,

I'm really stuck on this question.

At first I thought it was trivial but I have had second thoughts about that. Can someone help please.

If

then what is

I know that you want to see what I have done first but I really haven't done anything that I see as helpful.

If the first statement was true for all real x the second one would be also equal to 1.

But this is not the case so I really don't know where to start.

Thankyou.
