Homework Help: CALCULUS

Posted by Help asap!! plz on Friday, October 22, 2010 at 6:11pm.

Consider the function:
f(x) = x/(x^2 + 2)

(a) Determine the intervals on which the function is concave up. Enter the leftmost interval first (e.g. (1,2) would come before (3,4)).


(b) Determine the intervals on which the function is concave down. Enter the leftmost interval first.

i only got to figure out the first derivative. And i did figure out second derivative but it came out to be some thing very long and nasty. so please help!
f'(x)=((x^2+2)-2x)/(x^2 + 2)^2
