critical f(x)=((x^2+5x+4))/(x^2)

critical points

f (x) = \frac{( x ^{2} + 5 x + 4 )}{x ^{2}}

x = - \frac{8}{5}

Solution steps

\frac{x ^{2} + 5 x + 4}{x ^{2}}

Find where

f^{'} (x)

is equal to zero or undefined

x = - \frac{8}{5}, x = 0

Identify critical points not in

f (x)

domain

Domain of

\frac{x ^{2} + 5 x + 4}{x ^{2}} : x < 0 or x > 0

\frac{x ^{2} + 5 x + 4}{x ^{2}}

is not defined at

x = 0

, therefore:

x = - \frac{8}{5}
