critical f(x)=(x+7)/(x+4)

critical points

f (x) = \frac{x + 7}{x + 4}

None

Solution steps

\frac{x + 7}{x + 4}

Find where

f^{'} (x)

is equal to zero or undefined

x = - 4

Identify critical points not in

f (x)

domain

Domain of

\frac{x + 7}{x + 4} : x < - 4 or x > - 4

\frac{x + 7}{x + 4}

is not defined at

x = - 4

, therefore:

None

f (x) = 6 x - 12 - 3 x^{2}

y = 12 \cdot \frac{( 3 ) ( 2 )}{4}

12 x - 3 y = - 3

\frac{x + 5}{x - 3}

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