If you're given a graph of f', how can you tell where there are local min or max in f?
what does it mean when f'(x)=0?
what are the intervals where f'(x)>o and f'(x)<0?
what does it imply when and or the other way around?
maybe, i can't wait for your reply.. anyways, these are the interpretations..
if , then surely, f has a rel min or max at
suppose, and , then f assumes a rel min at ; for the other case, f assumes a relative max.. Ü
When f'(x)=0, that's a critical point. If f'(x)>0, then that's where f(x) is increasing; f'(x)<0, f(x) is decreasing.
I don't get what the last one mean.
Ok, so I got local max at x=2. Then I got min at x=4,x=8. Am I missing something for max because I didn't get the right answer.
