Need help on the following I can do easy ones of finding extremes like -x^3+2x^2 but these problems I'm having trouble figuring out what to do. Also how do I find absolute values?
a. Find the Interval on which the function is increasing and deceasing.
b. Then identify the functions local extreme values if any.
c. Which, if any, are absolute values?
1. x sq.(8-x^2)
2. x^(1/3) (x+8)
3. e^2x + e^-x
