critical f(x)=(5x^2)/(x^2-16)

critical points

f (x) = \frac{5 x ^{2}}{x ^{2} - 16}

x = 0

Solution steps

\frac{5 x ^{2}}{x ^{2} - 16}

Find where

f^{'} (x)

is equal to zero or undefined

x = 0, x = - 4, x = 4

Identify critical points not in

f (x)

domain

Domain of

\frac{5 x ^{2}}{x ^{2} - 16} : x < - 4 or - 4 < x < 4 or x > 4

\frac{5 x ^{2}}{x ^{2} - 16}

is not defined at

x = - 4, x = 4

, therefore:

x = 0
