Homework Help: college algebra

Posted by Zach on Wednesday, April 2, 2008 at 7:17pm.

Let f(x)= x^5/120 - x^3/6 + x

Find the local minima and maxima, then determine where the function is decreasing and increasing.

Basically, I just need to know how to type this correctly in my calculator so I can get the right minima and maxima.

I had:

local minima: f(-1.59)=-1.00
f(3.08)=.520
local maxima: f(1.59)=1.00
f(-3.08)=-.520
and

increasing : (-1.5, 1.5)
decreasing : (1.5, 3)
