critical 9x+7/x

critical points

9 x + \frac{7}{x}

x = - \frac{7}{3}, x = \frac{7}{3}

Solution steps

9 x + \frac{7}{x}

Find where

f^{'} (x)

is equal to zero or undefined

x = - \frac{7}{3}, x = \frac{7}{3}, x = 0

Identify critical points not in

f (x)

domain

Domain of

9 x + \frac{7}{x} : x < 0 or x > 0

9 x + \frac{7}{x}

is not defined at

x = 0

, therefore:

x = - \frac{7}{3}, x = \frac{7}{3}

What is the critical 9x+7/x ?
The critical 9x+7/x is x=-(sqrt(7))/3 ,x=(sqrt(7))/3
