How were you supposed to do b and c? The rest of the paper was easy I just couldn't get those two!

16b and c were terrible....
I only got 16b (iv) and the rest i was like.. wtfffffff. I thought i was going to get (iii) but apparently not -___-
For 16c, wth shit son this made absolutely no sense to me lmaooo. I got c>1/4 for (ii) cause I tried doing discriminant but I had no idea what to do for (i)

What did you guys get for 16a (ii)? i'm not sure if i did it right or not...

Haha this!! I managed to get C (ii) but I just could not work out (i) :O
Didn't get time to look over everything because I spent so long on 16, but provided no stupid mistakes like I usually do, the rest was all pretty good :)

for ci i used simultaneous equations with the two curves because they could both be rearranged to be in terms of xsquared and then just simplified. but ii i dont know how it couldve been >1/2
