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

critical points

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

y = 0, y = 4

Solution steps

\frac{y - 2}{y ^{2} - 2 y + 4}

Find where

f^{'} (y)

is equal to zero or undefined

y = 0, y = 4

Identify critical points not in

f (y)

domain

Domain of

\frac{y - 2}{y ^{2} - 2 y + 4} : - \infty < y < \infty

All critical points are in domain

y = 0, y = 4

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

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

\frac{5}{x ^{2} + 1}

f (x) = - x^{2} - 3

f (x) = 6 - x
