extreme f(x)= 1/(x(x-3)^2)

Solution

extreme points

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

Solution

Minimum (1, \frac{1}{4})

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < 0,

Decreasing

: 0 < x < 1,

Increasing

: 1 < x < 3,

Decreasing

: 3 < x < \infty

Plug

x = 1

into

\frac{1}{x ( x - 3 ) ^{2}} : \frac{1}{4}

Minimum (1, \frac{1}{4})
