critical f(x)=(ln(x))/(x^4)

critical points

f (x) = \frac{ln ( x )}{x ^{4}}

Solution steps

\frac{ln ( x )}{x ^{4}}

Find where

f^{'} (x)

is equal to zero or undefined

Identify critical points not in

f (x)

domain

Domain of

\frac{ln ( x )}{x ^{4}} : x > 0

\frac{ln ( x )}{x ^{4}}

is not defined at

x = 0

, therefore:

- 2 y - 10 + 2 x = 0

y - x = - 3

x - 3 y = - 2

f (x) = - \frac{1}{3} x^{2} + 4 x + 11

(0.3) m = 4
