extreme y=(x+2)/(x^2)

Solution

extreme

Solution

Minimum (- 4, - \frac{1}{8})

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < - 4,

Increasing

: - 4 < x < 0,

Decreasing

: 0 < x < \infty

Plug

x = - 4

into

\frac{x + 2}{x ^{2}} : - \frac{1}{8}
