extreme f(x)=(x-4)/(x^2)

Solution

extreme points

f (x) = \frac{x - 4}{x ^{2}}

Solution

Maximum (8, \frac{1}{16})

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < 0,

Increasing

: 0 < x < 8,

Decreasing

: 8 < x < \infty

Plug

x = 8

into

\frac{x - 4}{x ^{2}} : \frac{1}{16}

Maximum (8, \frac{1}{16})
