critical f(x)=x^3-12x

critical points

f (x) = 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 - 1 )}{( x ^{2} - 1 )}

\frac{2}{x + 2} + 3

p (w) = \frac{2}{3} w - 8

y = - 2 x - 1

e^{- x^{2}}
