Sal, ramping up on the knowledge bombing!

I still don’t understand inflection points. How do you prove that a point is an inflection point? Please reply to this! Thank you.

[@kwtan3814]

Maybe too late, was wondering the same, until i realise it has to be decreasing then increasing or vice versa, however it doesn't count when it hit 0, as it was neither increase nor decreasing. Hope you get my drift.

[@mariehill6547]

KW TAN yeah, I got there in the end. Thanks anyways!
