Best ResponseYou've already chosen the best response.0yeah, you're right. the second derivative is to find if it is a min or a max. http://en.wikipedia.org/wiki/Second_derivative

Best ResponseYou've already chosen the best response.0The way my teacher taught how to find the min and max is by using a calculator , but if there is an easier way by hand, I wanna know howw

Best ResponseYou've already chosen the best response.0How do I find the min and max using a calculator then?

Best ResponseYou've already chosen the best response.1if the function was in even degree has a max or a min or both like that i drawdw:1358815524977:dw

Best ResponseYou've already chosen the best response.0minimum: min{f(x) = x^35 x^2+3 x+12} = 3 at x = 3 max: max{f(x) = x^35 x^2+3 x+12} = 337/27 at x = 1/3
