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

f (x) = \frac{( x ^{2} - 16 )}{( 2 x ^{2} + 7 x - 15 )}

f (x) = x^{2} - 64

x e^{- x^{2} - y^{2}}

\frac{t ^{2}}{t - 2}

4 + x e^{- \frac{1}{2} x}
