Question

what part of the graph of f'(x) determines the inflection points of f(x)???

Answer 1

To find the inflection point you find the 2nd derivative of f(x) and then find x ( f''(x)=0 )

Answer 2

okay so the x intercepts of f'(x) are the inflection points on f(x) right?

Answer 3

The 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

Answer 4

`okay so the x intercepts of f'(x) are the inflection points on f(x) right?`
incorrect

Answer 5

okay i think i understand , where the tangent is zero on the graph of f'(x) is where f(s) has an inflection point

Answer 6

sorta, it has to be an extrema

Answer 7

the tangent slopes have to change from positive to negative, or vice versa

Answer 8

what do you mean by extrema ?

Answer 9

let's say we had this f ' (x) graph
