A cubic can have no stationary points, since a quadratic derivative can have no real solutions.
Wasn't that like the f'(x)>=5 question?

I initially had m=0,1,2,3 and m=1.

THANK GOD I CHECKED OVER MY ANSWERS.

Changed it to the correct m=0,1,2 and m=0,1. :D

To be honest, anybody who didn't include m=0 learnt nothing from methods this year.

If the previous question just bloody showed you that the derivative can be positive for all values of x, why the hell would you think in the very next question a cubic can't have NO stationary points?

Surely you should have understand the significance of f'(x) >0
ur funny, harsh cunt

I don't even remember this question, which one was it again?
