so i have a point of inflection at -1.86?

So this is a local maximum?

somthing seems wrong , can anyone point out what it is?

is that because doesnt exist?

Are you able to tell me or direct me to somewhere where i may learn the process of finding max/mins , i have been trying to find somwhere but i can't. My textbook is worthless.Im getting really frustrated trying to work these out i just don't understand them. - Sep 4th 2009, 05:50 PMel123
