Maths C1 - Sketching graphs

Not a question about them per se but more of what is expected for a student to do if a question came up on the exam.

In the textbook my school gave me it says to only show the points where the curve cuts the axes and, obviously, the general shape of the curve and all that and from that I use you draw axes anyway and then draw a standard quadratic curve and then find out the points - right?

However, my teacher is teaching it in a different manner whereby we work out some point which are quite easily worked out from the equation given however they don't cross the axes so are they even needed? I realise it might be good to do that but I want to learn what the examiners want to see to get the marks and not get it wrong when I thought it was right.
Yep, they're needed :smile:.

I'd sketch all the important peices of information. It depends on the question though. You know, where it crosses x and y axes, turning points, how it looks as x gets to a large negative and large positive.
