1. I just want to know in the graph scetching problems, does the shape of the graph need to be very accurate or do you just need the kinda correct shape and the coordinates? I have made an example below for a question. Is both my answers going to get full marks? You can see 2 is much more accurate.

They would both get full marks, important things are having turning points labelled and in the correct quadrant and roots in the correct position.
3. yeah you've just got to show a shape that meets the graph at positive and negative points where it is supposed to pretty much...

If you had f(x) and f(2x) drawn exactly the same with the different co-ordinates marked then you would get full marks

Thanks guys, but look at second part, I have attached mark scheme, it says stuff about gradient and cusp?

5. Man, you guys are quick though. Love it!

Is this for a modulus graph?

Yes same paper same question, second part of it.

Alright, so the only addendum is that key features are turning points in correct quadrants, roots in correct positions and for modulus graphs, make sure the "turning points" are not perfectly curved, i.e: don't have 0 gradients.

I'm sorry but can you give me an example about the modulus?

The markscheme you linked is an example.
