Homework Statement
f(x) = x^3 + 12x^2 - 27x + 11
Absolute Maximum
Absolute Minimum
on the interval [-10,0]
(there are 3 different interval sets, but if I can do this one, I think I can figure out the rest.)
Homework Equations
Derivative, set equal to 0, then solve for the problem, but...
I see now! I really need to get more comfortable with the quotient rule. I think I end up running myself in circles too often because I try to use the product rule, and then can't alter the problem to look like it would, if I had used the quotient rule.
Thank you very much!
Homework Statement
(16x)/(x^2+4) for -5 (less than OR equal to) x (less than OR equal to) 5
Homework Equations
Set the derivative of the equation equal to 0, solve for x to find the critical points, then plug and check for validity.
