Best ResponseYou've already chosen the best response.0well at 4,4 it's an inflection point meaning from positive to negative or negative to positive

Best ResponseYou've already chosen the best response.1I just wanna first make sure I understand the language they're using. x<2, falling concave up. Does that mean the slope is falling? Or that the function is falling? Hmm I think it means the function is falling, because if the slope was falling, it would be concave down, as you have drawn it in the picture. See how you have a HAT shape before x=2? Isn't that concave down? Am I looking at it correctly? :D heh

Best ResponseYou've already chosen the best response.0lol well x<2? i read it as any function less than two. and the curve is "falling" concave up

Best ResponseYou've already chosen the best response.1From 2 to 4, the function needs to be RISING the entire time, it can't dip downward, here is an example.

Best ResponseYou've already chosen the best response.1from BEFORE 2, it was concave up, it continues to be concave up all the way til 4. With a horizontal tangent at 2.

Best ResponseYou've already chosen the best response.1dw:1355274652299:dwSee how the slope changes from increasing to decreasing? The FUNCTION is still increasing, but now the SLOPE is decreasing, creating a HAT instead of a bowl.

Best ResponseYou've already chosen the best response.1CCU = Concave Up CCD = Concave Down In case there was any confusion about that :)

Best ResponseYou've already chosen the best response.1Can you picture how it will end? :D We have another tangent at x=6 right? Then the instructions say umm Falling Concave Down for the rest of the way... So we'll continue to have a nice HAT shape, with the top of the hat being at x=6.
