critical (7x-2)/(x+6)

critical points

\frac{7 x - 2}{x + 6}

None

Solution steps

\frac{7 x - 2}{x + 6}

Find where

f^{'} (x)

is equal to zero or undefined

x = - 6

Identify critical points not in

f (x)

domain

Domain of

\frac{7 x - 2}{x + 6} : x < - 6 or x > - 6

\frac{7 x - 2}{x + 6}

is not defined at

x = - 6

, therefore:

None

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

\frac{x ^{2} - 5 x + 6}{x + 3}

(- 2.5) (4)

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

f (x) = x^{2} - 4 x + 4
