critical f(x)=(x^2-1)/(x^2+2x-3)

critical points

f (x) = \frac{x ^{2} - 1}{x ^{2} + 2 x - 3}

None

Solution steps

\frac{x ^{2} - 1}{x ^{2} + 2 x - 3}

Find where

f^{'} (x)

is equal to zero or undefined

x = - 3

Identify critical points not in

f (x)

domain

Domain of

\frac{x ^{2} - 1}{x ^{2} + 2 x - 3} : x < - 3 or - 3 < x < 1 or x > 1

\frac{x ^{2} - 1}{x ^{2} + 2 x - 3}

is not defined at

x = - 3

, therefore:

None
