The quality that makes living organisms different from dead ones.

OpenStudy (anonymous):

Playing a productive role to improve future generations. And people like us are certainly productive since we are spending time in helping other individuals rather than posting on facebook lol

OpenStudy (anonymous):

Ooooh, but if you aren't on FB then you have no life...well that's how the rest of the world sees it.

OpenStudy (anonymous):

you know whats funny, People updating their status after every 5 mins like anyone cares.... haha

OpenStudy (anonymous):

is there anyone who can help me out with a business calculus question here ?

OpenStudy (anonymous):

I can try. What's up?

OpenStudy (anonymous):

find the relative extrema of the function if they exist. f(x) = x^3-3x^2 +1

OpenStudy (anonymous):

Ew...extrema. I can probably get it, but I am about to leave work and lose my comp. I would post it on the board. Once I get back, if you don't have the answer, I will get it for you.

OpenStudy (anonymous):

k thanks

OpenStudy (anonymous):

wow man, you are simply awesome since you explained the question at its simplest.

OpenStudy (anonymous):

Thanks jabbasi1

OpenStudy (anonymous):

set f'(x) to 0 and find the critical points, 3x^2-6x=0 x(3x-6), x=0, x=2 substitute each x value into the original equation, solve for y f(0)=1 f(2)=-3 X=0 is a maximum x=2 is a minimum

OpenStudy (anonymous):

can i ask you another question ?

OpenStudy (anonymous):

I can give it a shot

OpenStudy (anonymous):

determine where the given function is invreasing and where it is decreaseing F9x)= x^3-12x+2

OpenStudy (anonymous):

f(x)*

OpenStudy (anonymous):

First take the derivative, then find the roots by factoring. This will give you your turning points. Then arbitrarily pick test values and plug them into f'(x) to determine whether it is increasing or decreasing.

thanks
