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

critical points

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

x = - \frac{2}{5}, x = \frac{2}{5}

Solution steps

5 x + \frac{2}{x}

Find where

f^{'} (x)

is equal to zero or undefined

x = - \frac{2}{5}, x = \frac{2}{5}, x = 0

Identify critical points not in

f (x)

domain

Domain of

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

5 x + \frac{2}{x}

is not defined at

x = 0

, therefore:

x = - \frac{2}{5}, x = \frac{2}{5}

f (x) = 8 x - 2

y = - 3 x + 2

1 + \frac{1}{x - 1}

\frac{2 x ^{2} - 8 x + 5}{( x - 2 ) ^{2}}

y = ln (x^{2} - 8 x)

The critical f(x)=5x+2/x is x=-sqrt(2/5),x=sqrt(2/5)
