monotone f(x)=((x-6))/((x+6))

monotone intervals

f (x) = \frac{( x - 6 )}{( x + 6 )}

Increasing : - \infty < x < - 6, Increasing : - 6 < x < \infty

Solution steps

f^{'} (x) = \frac{12}{( x + 6 ) ^{2}}

Find intervals:

Increasing

: - \infty < x < - 6,

Increasing

: - 6 < x < \infty

Increasing : - \infty < x < - 6, Increasing : - 6 < x < \infty

1 - x

f (x) = \frac{( 3 + 4 x )}{1 - 5 x}

(- 2, 7), (- 2, - 8)

7 x + y = 6

f (x) = x + \frac{7}{x}

What is the monotone f(x)=((x-6))/((x+6)) ?
The monotone f(x)=((x-6))/((x+6)) is Increasing:-infinity <x<-6,Increasing:-6<x<infinity
