critical f(x)=((2x-1))/(x^2-4x-5)

critical points

f (x) = \frac{( 2 x - 1 )}{x ^{2} - 4 x - 5}

None

Solution steps

\frac{2 x - 1}{x ^{2} - 4 x - 5}

Find where

f^{'} (x)

is equal to zero or undefined

x = - 1, x = 5

Identify critical points not in

f (x)

domain

Domain of

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

\frac{2 x - 1}{x ^{2} - 4 x - 5}

is not defined at

x = - 1, x = 5

, therefore:

None
