critical 9x+1/x

Solution

critical points

9 x + \frac{1}{x}

Solution

x = - \frac{1}{3}, x = \frac{1}{3}

Solution steps

9 x + \frac{1}{x}

Find where

f^{'} (x)

is equal to zero or undefined

x = - \frac{1}{3}, x = \frac{1}{3}, x = 0

Identify critical points not in

f (x)

domain

Domain of

9 x + \frac{1}{x} : x < 0 or x > 0

9 x + \frac{1}{x}

is not defined at

x = 0

, therefore:

x = - \frac{1}{3}, x = \frac{1}{3}

Popular Examples

critical 6x^3-18x+10 critical points

6 x^{3} - 18 x + 10

critical f(x)= x/((x-1))critical points

f (x) = \frac{x}{( x - 1 )}

critical f(x)=4x^3-36x critical points

f (x) = 4 x^{3} - 36 x

critical 3cos(pi(x+2))-1 critical points

3 cos (π (x + 2)) - 1

critical (x^2-x)/(8x^2+1)critical points

\frac{x ^{2} - x}{8 x ^{2} + 1}
