monotone f(x)=(2x-8)^{2/3}

monotone intervals

f (x) = (2 x - 8)^{\frac{2}{3}}

Decreasing : - \infty < x < 4, Increasing : 4 < x < \infty

Solution steps

f^{'} (x) = \frac{4}{3 ( 2 x - 8 ) ^{\frac{1}{3}}}

Find intervals:

Decreasing

: - \infty < x < 4,

Increasing

: 4 < x < \infty

Decreasing : - \infty < x < 4, Increasing : 4 < x < \infty

f (x) = \frac{4 x + 9}{3 x - 4}

y = \frac{1}{x}

2 x^{2} + 12 x

sec (x)

f (x) = x^{3} + 6 x^{2} + 16

What is the monotone f(x)=(2x-8)^{2/3} ?
The monotone f(x)=(2x-8)^{2/3} is Decreasing:-infinity <x<4,Increasing:4<x<infinity
