critical f(x)=(x-2)/(x^2+5x+4)

critical points

f (x) = \frac{x - 2}{x ^{2} + 5 x + 4}

x = 2 - 32, x = 2 + 32

Solution steps

\frac{x - 2}{x ^{2} + 5 x + 4}

Find where

f^{'} (x)

is equal to zero or undefined

x = 2 - 32, x = 2 + 32, x = - 4, x = - 1

Identify critical points not in

f (x)

domain

Domain of

\frac{x - 2}{x ^{2} + 5 x + 4} : x < - 4 or - 4 < x < - 1 or x > - 1

\frac{x - 2}{x ^{2} + 5 x + 4}

is not defined at

x = - 4, x = - 1

, therefore:

x = 2 - 32, x = 2 + 32

\frac{3}{x + 1}

f (x) = 6 + 2^{7 x - 1}

f (x) = (x - 5)^{3}

s (t) = \frac{7 t}{sin ( t )}
