critical (x^2+x+2)/(x-1)

critical points

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

x = - 1, x = 3

Solution steps

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

Find where

f^{'} (x)

is equal to zero or undefined

x = - 1, x = 3, x = 1

Identify critical points not in

f (x)

domain

Domain of

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

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

is not defined at

x = 1

, therefore:

x = - 1, x = 3

\frac{5 x}{x + 8} - 8

y = \frac{2}{5} x - 5

6 x

f (x) = x^{5} + 1

f (x) = \frac{∣ x ∣}{x ^{2}}
