critical x^3-12x^2-27x+8

critical points

x^{3} - 12 x^{2} - 27 x + 8

x = - 1, x = 9

Solution steps

x^{3} - 12 x^{2} - 27 x + 8

Find where

f^{'} (x)

is equal to zero or undefined

x = - 1, x = 9

Identify critical points not in

f (x)

domain

Domain of

x^{3} - 12 x^{2} - 27 x + 8 : - \infty < x < \infty

All critical points are in domain

x = - 1, x = 9

x^{4} - 2 x^{3}

2^{x}

f (x) = \frac{( x - 3 ) ^{2}}{x - 5}

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

f (x) = \frac{1}{( x + 1 ) ( x + 2 )}
