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

critical points

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

x = - 2, x = 2

Solution steps

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

Find where

f^{'} (x)

is equal to zero or undefined

x = - 2, x = 2, x = 1, x = 2

Identify critical points not in

f (x)

domain

Domain of

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

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

is not defined at

x = 1, x = 2

, therefore:

x = - 2, x = 2

What is the critical f(x)=(2x)/(x^2-3x+2) ?
The critical f(x)=(2x)/(x^2-3x+2) is x=-sqrt(2),x=sqrt(2)
