When they say : Describe the geometrical transformation that maps the curve with equation y=x^2-6x+11 onto curve y=x^2 do they mean going from y=x^2-6x+11 --------> y=x^2 ???

-(x-2)(x-5)(x+5)
What are the values of x?

The minus only effects (x-2) so its (-x+2) or (2-x) so x is 2 for that one

One of the worst things to lose marks on is not putting a closing line on verify questions so remember to say "therefore D lies on the circle" or whatever. Loads of my friends forget...

Does anyone ever do the last question first? Like getting the supposedly hardest question done before the rest?

Why? If you're worried about time, then you'll be able to do more easier question in the same time and get more marks.

Anyway, if you don't know the last one, you're going to on that for ages and you'll be worried about it while doing the rest of the paper. Bad idea.
