If f'(a) = 0, we can say that is relative extrema at f(x) at x=a, right?

OpenStudy (anonymous):

yes

@phi

OpenStudy (phi):

what is the question? You do know to find a min or max of f(x) you would find df/dx and set equal to 0. I would look at the graph for f'(x) and look for when it's zero also, the points on f'(x) where its slope is zero are where f''(0)=0. These are inflection points.

OpenStudy (anonymous):

the question is in the creenshot

OpenStudy (phi):

Yes, I see the question. But what do you not understand so that you can answer it ?

OpenStudy (anonymous):

how do i figure out if the relative exterma is 1 or 0

OpenStudy (phi):

relative extrema is another way to say local minimum or local max. In calculus they drum it into your head (hopefully!) that a max (for example) is where the slope of the tangent line is zero, i.e. where f'(x) is 0 Look at your graph. Do you see any places where the graph crosses the x-axis (i.e. its y value is 0, meaning f'(x) is zero)

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

so that means it would be 1

OpenStudy (phi):

It means statement I is true. There is an extrema at x=0 there is also a max/min at x=2, but they don't mention it. However, they do mention an inflection point. Did you learn how to identify an inflection point ?

OpenStudy (anonymous):

uhh not that i remember lol could you explain?

OpenStudy (phi):

The second derivative is zero

OpenStudy (anonymous):

so this one does not have an inflation

OpenStudy (phi):

inflection (inflation is something else) to find where the second derivative is zero, look for local min or max on the graph of the first derivative.

OpenStudy (anonymous):

idk what youre trying to say..

OpenStudy (anonymous):

im confused

OpenStudy (anonymous):

im going with it has an inflection at 1

OpenStudy (phi):

I think this question is asking for *all* the statements that are true. Two of them are true.

OpenStudy (loser66):

agree with phi

OpenStudy (loser66):

go backward, forget about the graph. By definition, f has extrema at the points where f' =0, right? The graph is f' (not f) and to the graph, f' =0 at x =0 and x =1, so x =0 and x =1 are relative extrema. Period.
