I'm sure you use the answer from 3di

You solve g'(x) = 0 when c = 4/3 to get x = -2/3

Then solve g(-2/3) = -2/3 for k to get k = -10/27

I solved g(x)=x and solved for k. Then I set derivative equal to 0 and solved for x. Substituted this value back into equation for k and voila. Don't remember what I got. I'll redo it now...

I made a really silly arithmetic error for that question >.> but yes I would've gotten -10/27 as well.

Guys, I'm really stressed out and disappointed with my predicted results so far. I'm certain that I've lost at least 10 (could be more) marks on both exams. Is this enough to get a raw 40???

Hmmm well for some reason I think I got -10/27 as well, so perhaps I didn't use my answer from i), (Hopefully!)
