critical f(x)=x^2+(128)/x

critical points

f (x) = x^{2} + \frac{128}{x}

x = 4

Solution steps

x^{2} + \frac{128}{x}

Find where

f^{'} (x)

is equal to zero or undefined

x = 4, x = 0

Identify critical points not in

f (x)

domain

Domain of

x^{2} + \frac{128}{x} : x < 0 or x > 0

x^{2} + \frac{128}{x}

is not defined at

x = 0

, therefore:

x = 4

f (x) = 5 a x - 2 x^{2}

\frac{6 x ^{2} + 2 x - 3}{x - 4}

f (x) = 2 x^{3} + 3 x^{2} - 72 x + 7

x e^{6 x^{2}}

f (x) = x (x - 6)
