In class today we were doing a problem where we were given the graph of f (the derivitive of F). The domain was -3<x < or = 8 f(8)=0 and f had changed from positive <8 to 0, indicating a probable relative max (the function looked like a sinusoid, but the points after 8 were not graphed or included in the domain) Therefore my question is, is 8 a relative max of F in that domain? or is not enough info there (i.e. it could have just bounced)? My reasoning for it being a rel max is that it is a max value in the window. What do you think?
