extreme f(x)=((x+1))/(x^2)

Solution

extreme points

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

Solution

Minimum (- 2, - \frac{1}{4})

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < - 2,

Increasing

: - 2 < x < 0,

Decreasing

: 0 < x < \infty

Plug

x = - 2

into

\frac{x + 1}{x ^{2}} : - \frac{1}{4}

Minimum (- 2, - \frac{1}{4})
