I only did domain.

Did they ask for range?!

I can see that we got the same graph values but I messed up and put y=X instead of f(x)=X, how badly will I be penalised for this? :frown:

For the first part I thought it was to 2 or 3 not 1

IDK I cant remember :tongue:

Did people get 0.6 and 0.4 for the matrices question can't remember what way round

You wont lose any marks. Complete worse case scenario you lose 1 mark.

I found that paper pretty fine. The circle question is based on the alt segment theorem and the fact that angles in a triangle = 180. By working out each of the angles on the tangent on the smaller circle that crosses through the bigger one. Eventually you get an angle around the point in the middle that = 180 - 2a - 2b.

Answer:
y=-x^2 -1<x<=2
y=-4 2<x<=3
y=4x-16 3<x<=4

That`s exactly what I got except I did for each value:

X<Y<X With the first < being equal to or smaller than and then the second < being smaller than.

Wil I lose marks for including an < Equal to or sign for the first of each domain?

anyone else get something like sqrt(300) + sqrt(98) for the surd question?

i had √108 + √98

Thats awesome. but I made another mistake, instead of including just is greater than is is smaller than inequalities, for 1 of the two inequality signs in all 3 answers I put is greater than or equal to -.-

IDK why the hell I was such a dumb-arse :frown:

How many marks would I lose for that do you think? :frown:

Did people get y=1/5x +2 2/5 for the equation of the normal question

I felt like I was aceing the middle questions, then got to that circle one and just wanted to put my head in my hands.

I think that was a pretty tough paper, so hopefully grade boundaries are low. It's usually only around 50% overall (give or take a few marks) to get an A, which is what I think I managed to scrape (hopefully more but I'd be happy with an A), so...fingers crossed the calc paper is easier - or at least, not harder.
