critical f(x)=x+9/x

Solution

critical points

f (x) = x + \frac{9}{x}

Solution

x = - 3, x = 3

Solution steps

x + \frac{9}{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

x + \frac{9}{x} : x < 0 or x > 0

x + \frac{9}{x}

is not defined at

x = 0

, therefore:

x = - 3, x = 3

Popular Examples

range of sqrt(-x)+5 range

- x + 5

domain of f(x)=sin((x+1)/(x-1))domain

f (x) = sin (\frac{x + 1}{x - 1})

intercepts of (5x^2-10x+1)/(x-2)intercepts

\frac{5 x ^{2} - 10 x + 1}{x - 2}

range of f(x)= 2/(2x-5)range

f (x) = \frac{2}{2 x - 5}

midpoint (-2,-2),(4,8)midpoint

(- 2, - 2), (4, 8)
