Best ResponseYou've already chosen the best response.0To find the inflection point you find the 2nd derivative of f(x) and then find x ( f''(x)=0 )

Best ResponseYou've already chosen the best response.0okay so the x intercepts of f'(x) are the inflection points on f(x) right?

Best ResponseYou've already chosen the best response.1The extrema of f ' (x) have the same x coordinates of the roots of f '' (x), which is also where the inflection points on f(x) have the same x coordinates

Best ResponseYou've already chosen the best response.0okay i think i understand , where the tangent is zero on the graph of f'(x) is where f(s) has an inflection point

Best ResponseYou've already chosen the best response.1sorta, it has to be an extrema

Best ResponseYou've already chosen the best response.1but it's not a local min and not a local max

Best ResponseYou've already chosen the best response.1we need something like this or this dw:1440028990706:dw

Best ResponseYou've already chosen the best response.0okay so where ever the graph of f'(x) has a local max or min the graph of f(x) has an inflection point ?

Best ResponseYou've already chosen the best response.1"extrema" is a way to say "min or max" it's the extreme portion of the graph, so to speak
