critical f(x)=(x^2+x+1)/x

critical points

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

x = - 1, x = 1

Solution steps

\frac{x ^{2} + x + 1}{x}

Find where

f^{'} (x)

is equal to zero or undefined

x = - 1, x = 1, x = 0

Identify critical points not in

f (x)

domain

Domain of

\frac{x ^{2} + x + 1}{x} : x < 0 or x > 0

\frac{x ^{2} + x + 1}{x}

is not defined at

x = 0

, therefore:

x = - 1, x = 1

f (x) = \frac{2 x ^{2}}{x ^{2} - 16}

F (a, b) = a^{6} - 64 b^{6}

x^{3} - 2 x^{2} + x - 2

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

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

What is the critical f(x)=(x^2+x+1)/x ?
