(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

(a) Find the intervals on which f is increasing or decreasing.

(b) Find the local maximum and minimum values of f.

(c) Find the intervals of concavity and the inflection points.

x^{2}/(x^{2}+3)

2. Relevant equations

3. The attempt at a solution

a) I find that

f'(x)=6x/(x^{2}+3)^{2}

I am stuck because (x^{2}+3)^{2}has no solutions and I don't know how to define x in order to proceed further.

If anybody can help me out understanding this, I will be very thankful.
