critical f(x)=2x+(300000)/x

critical points

f (x) = 2 x + \frac{300000}{x}

x = - 10015, x = 10015

Solution steps

2 x + \frac{300000}{x}

Find where

f^{'} (x)

is equal to zero or undefined

x = - 10015, x = 10015, x = 0

Identify critical points not in

f (x)

domain

Domain of

2 x + \frac{300000}{x} : x < 0 or x > 0

2 x + \frac{300000}{x}

is not defined at

x = 0

, therefore:

x = - 10015, x = 10015

f (x) = - 2 x^{2} - y^{2} + 8 x + 10 y - 5 x y

f (x, y) = x^{2} + y^{2} - 2 x

f (x) = x^{2} - 6 x - 7

f (x, y) = 2 y^{3} + x^{2} y

f (x) = x^{2} + 2 x + 2
