Testing for concavity? (1 Viewer)

[old.skool.kid]

What are your opinions on testing for concavity in curve sketching?
Like in the 2007 it had a 10 MARKER, do you think they would have taken a mark off if you didnt test for it?
I got a mark off in the trial for not doing it, but i think its pretty pointless and ive never done it..

Test concavity. It takes 2 seconds and 1 mark could be difference between a band 5 and 6 hehe.

they generally expect you too regardless

I always test for it.

Always, always, ALWAYS do as MUCH working out for curve sketching; x-intercepts, y-intercepts, label every stationary point, inflexion point, EVERYTHING. That is, unless your running out of time, then do the bare minimum, but that includes testing for concavity anyway.

are u all refering to just proving its a max or a min? or like testing POI so that the sign changes
