I think 2,4 are point if inflection
because point of inflection means f''(c)=0
But the graph is of f'(x) already 
We have to check only where slope of f'(x) become 0 and that are 2,4

how when I am not given the equation of the function?

pawanyadav · Answer

From graph

pawanyadav · Answer

If you know the graph of a function with points  you can tell anything about the function............ @StudyGurl14

amistre64 · Answer

points of inflection will appear in an interval that has a tangent slope of 0 at each end.

amistre64 · Answer

we know (or can assume) 3 points on the graph that look as if they would have a slope of 0 ...

amistre64 · Answer

doh! ... the given graph is f'

amistre64 · Answer

the inflection points tend to be where the derivative, of the derivative, is equal to zero .... and determining if the slope changes sign i believe

studygurl14 · Answer

but how do I find the second derivative with only the graph of f ' ?

amistre64 · Answer

what does a derivative of a function tell us?  something about the slope at a point right?
