It's wrong as Arsey explained but probably only 1 mark lost lol

but domain is x>1 and so x cannot= 1

you have to consider that. so range >3

guys i have a question..

on question 4 part b a simple question like that couldnt possibly be worth 5 marks cause its so simple. wat i did was use the equation he gave us and replace it in dy/dx of part a. i reached really far in the process and i almost got it actually. has anyone done the same???? wat confused me was the way the question was asked. it sounded like he was talking about dy/dx of part (A). wat do u guys think? and if im wrong i lose 5 marks ryt?????

You 're predictions don't make sense at all. If 100 were 70-71 then the grade for an A would be much lower than 61-63. You're saying that 93% raw makrs will get 100% UMS, and 84% raw for 80% UMS.

PS: this is an important tool i have given you guys...i must be rewarded for it!!

It was made by someone else, did you remove the name so you could claim credit?

no way am i claiming that it is made by me.i dont think i mentioned that it is made made by me...did i???...i dont even know how it is supposed to be done. i am just passing on the good work done by someone to those who need it.

and i think i have just been negged by you. well i wasnt 'rep fishing' as you claim. i didnt mean 'reps' when i said reward. all i wanted is a thank you!

i wonder why evertone thinks about reps and negs....chill out and lets be friends and help each other

Yes, it was me

I'm sorry for the misunderstanding.. It's my bad. I think I just woke up on the wrong side of the bed this morning

That tool is great though Think I'll use it once our results are released

sorry, how? it's clearly two separate parts of the question

Because it says "given that"
it seemed to suggest that you should sub in tany into where x is in the answer to the previous q!

Having spoken to my students I would be amazed if the boundary for 80UMS is anywhere near 60. I am going for 55/75. Initially, I thought lower, but in reflection there were quite a lot of easy marks/questions.
