i think i got y=2x+10
3. what did everyone get for the completing the square one,then finding the maximum point? was it (3,22)?
4. For a couple of questions I wrote a couple of methods/answers - would the examiner mark all my working - or would I get 0 as I wrote more than one method?
Thanks
5. I got that duncat
6. For that question 4+12x+2x^2, I read that as 12x^2... will I get carried workings for the next question? I completed the square for it 100% correctly just misread the question...
7. [QUOTE=duncant;64915977]what did everyone get for the completing the square one,then finding the maximum point? was it (3,22)?

Thats what i put... Wasnt sure about the minus in front of the whole thing but i put (3,22) and i think i put something like -(x-3)^2+22

I think i put -2(x-3)^2+22
9. (Original post by julesaquilina)
i think i got y=2x+10
I thought as it was parallel to the first tangent that it was y=3x+10 as for the first tangent I got a gradient of 3
10. [QUOTE=duncant;64916135]
(Original post by julesaquilina)
I think i put -2(x-3)^2+22
I got 3,22 as well
11. when translating the curve by vector [3,0], was the new curve supposed to be drawn on the left or the right of the original?
12. The answer to the first one was 4x^2 - 9 ?
13. How are the maths grades calculated?
14. What was the answer for 2^k surds question with 5x 4^2/3 + 3x14^1/3?
15. [QUOTE=duncant;64916135]
(Original post by julesaquilina)
I think i put -2(x-3)^2+22
yes actually i put -2 as well
16. what did everyone get for question 9 which was the inequality of k to have two real roots?
17. Were you meant to sketch the translation graph. I think it was just explaining it.
18. pretty sure it was just explaining
19. Whats the general consensus? Did everyone find it as hard as I did?
