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

y=(2x+1)/[tex]\sqrt{x^2+1}[/tex]

Find where are the asymptotes, where is it increasing increasing/decreasing, ect.....

2. Relevant equations

3. The attempt at a solution

when I took the first derivative (im trying to find where it increases/decrease), I got

dy/dx = [tex]\frac{2x^2-x+2}{(x^2+1)\sqrt{x^2+1}}[/tex]

but there isn't any roots for this function... so what does that mean?
