monotone f(x)=((x-3))/((x+3))

monotone intervals

f (x) = \frac{( x - 3 )}{( x + 3 )}

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

Solution steps

f^{'} (x) = \frac{6}{( 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 f(x)=((x-3))/((x+3)) ?
The monotone f(x)=((x-3))/((x+3)) is Increasing:-infinity <x<-3,Increasing:-3<x<infinity
