critical f(x)=(x^2+8x-4)/(x-2)

critical points

f (x) = \frac{x ^{2} + 8 x - 4}{x - 2}

x = - 2, x = 6

Solution steps

\frac{x ^{2} + 8 x - 4}{x - 2}

Find where

f^{'} (x)

is equal to zero or undefined

x = - 2, x = 6, x = 2

Identify critical points not in

f (x)

domain

Domain of

\frac{x ^{2} + 8 x - 4}{x - 2} : x < 2 or x > 2

\frac{x ^{2} + 8 x - 4}{x - 2}

is not defined at

x = 2

, therefore:

x = - 2, x = 6

What is the critical f(x)=(x^2+8x-4)/(x-2) ?
The critical f(x)=(x^2+8x-4)/(x-2) is x=-2,x=6
