Sorry for posting in the middle of them earlier without realising you weren't finished >.>
Thanks again!

I used conditional prob for that q too but I trust TT's answers.
According to this I only lost 12 marks.  Hopefully when VCAA marks it it stays that way, or at least enough to get a high A!
That's so great for me, I'm over the moon.

Question 1 e iii should only have one section. the function of f(X) is only available for R+ U {0}. by making it a composite function you still need to adhere to f(x)'s domain. And even if it was a modulus, the mod causes a symetrical reflection in the y axis.
