critical 3x+(27)/x

Solution

critical points

3 x + \frac{27}{x}

Solution

x = - 3, x = 3

Solution steps

3 x + \frac{27}{x}

Find where

f^{'} (x)

is equal to zero or undefined

x = - 3, x = 3, x = 0

Identify critical points not in

f (x)

domain

Domain of

3 x + \frac{27}{x} : x < 0 or x > 0

3 x + \frac{27}{x}

is not defined at

x = 0

, therefore:

x = - 3, x = 3

Popular Examples

line m=-7/2 ,(-4,-5)line

m = - \frac{7}{2}, (- 4, - 5)

monotone f(x)=x^4-25x^2 monotone intervals

f (x) = x^{4} - 25 x^{2}

shift-cos(x)shift

- cos (x)

amplitude of f(t)=3cos(4t-(3pi)/4)+2 amplitude

f (t) = 3 cos (4 t - \frac{3 π}{4}) + 2

domain of (x-1)/(x+1)domain

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