critical x^3-12x

critical points

x^{3} - 12 x

x = - 2, x = 2

Solution steps

x^{3} - 12 x

Find where

f^{'} (x)

is equal to zero or undefined

x = - 2, x = 2

Identify critical points not in

f (x)

domain

Domain of

x^{3} - 12 x : - \infty < x < \infty

All critical points are in domain

x = - 2, x = 2

f (x) = \frac{x ^{2} - 8 x - 9}{3 x ^{2} + x - 2}

6 x - 4 y = 18

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

f (x) = \frac{x + 4}{x - 5}

f (x) = (5 - x) e^{- x}
