monotone (x+1)/(x+3)

monotone intervals

\frac{x + 1}{x + 3}

Increasing : - \infty < x < - 3, Increasing : - 3 < x < \infty

Solution steps

f^{'} (x) = \frac{2}{( x + 3 ) ^{2}}

Find intervals:

Increasing

: - \infty < x < - 3,

Increasing

: - 3 < x < \infty

Increasing : - \infty < x < - 3, Increasing : - 3 < x < \infty

What is the monotone (x+1)/(x+3) ?
The monotone (x+1)/(x+3) is Increasing:-infinity <x<-3,Increasing:-3<x<infinity
