critical f(x)=x+4/x

Solution

critical points

f (x) = x + \frac{4}{x}

Solution

x = - 2, x = 2

Solution steps

x + \frac{4}{x}

Find where

f^{'} (x)

is equal to zero or undefined

x = - 2, x = 2, x = 0

Identify critical points not in

f (x)

domain

Domain of

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

x + \frac{4}{x}

is not defined at

x = 0

, therefore:

x = - 2, x = 2

Popular Examples

y = 3 x + 3

domain of f(x)=sqrt(x^3-4x^2+3x)domain

f (x) = x^{3} - 4 x^{2} + 3 x

inverse of f(x)=(ln(x))^5 inverse

f (x) = (ln (x))^{5}

distance (-1,12),(1,0)distance

(- 1, 12), (1, 0)

intercepts of x^2+5 intercepts

x^{2} + 5
