critical 2x+(1936)/x

critical points

2 x + \frac{1936}{x}

x = - 222, x = 222

Solution steps

2 x + \frac{1936}{x}

Find where

f^{'} (x)

is equal to zero or undefined

x = - 222, x = 222, x = 0

Identify critical points not in

f (x)

domain

Domain of

2 x + \frac{1936}{x} : x < 0 or x > 0

2 x + \frac{1936}{x}

is not defined at

x = 0

, therefore:

x = - 222, x = 222

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

\frac{1}{x ^{2} - 4}

(4, 2), (8, 5)

\frac{x + 3}{x - 5}
