this is hard to explain because I can't post pictures of the two graphs, but I tried to draw them in paint. Here are the graphs: http://img.photobucket.com/albums/v629/ussjt/math.jpg(adsbygoogle = window.adsbygoogle || []).push({});

1)

the question asks estimate f '(0), f '(2), f '(5), f '(7)

when looking at at graph how do you determine the f '? I am confused about how to going about finding it.

2) at what points does the derivative exist? (how can you determine this?)

then sketch the derivative of s(the y-axis) (confused by the meaning)

Any help would be great.
