Hi there, I've attached the paper... just started it and it's fairly simple but for the second Q I don't understand the funny letters and symbols meaning I can't do the question!

I've tried to google etc them, there's noooo trace in my textbook I was wondering if someone could tell me what they are and how to use them in relation to the question.

Thanks very much in advance

I think it means sketch 4^x when x is real and positive (not totally sure though). If you have the edexcel book I think there's a symbol glossary at the back.

It basically means that x is an actual number. This includes 1, -1, pi, sqrt of 2 etc. The only thing it excludes are imaginary numbers which you'll come across if you do FP1.
