critical f(x)=(3x^2)/(x^2-16)

critical points

f (x) = \frac{3 x ^{2}}{x ^{2} - 16}

x = 0

Solution steps

\frac{3 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{3 x ^{2}}{x ^{2} - 16} : x < - 4 or - 4 < x < 4 or x > 4

\frac{3 x ^{2}}{x ^{2} - 16}

is not defined at

x = - 4, x = 4

, therefore:

x = 0

\frac{x - 3}{x}

f (x, y) = (9 - x) (9 - y) (x + y - 9)

+ \frac{x}{3 x + 4}

f (x) = 8 ln (x) - x^{2}

f (x) = \frac{x ^{4}}{4} - \frac{x ^{3}}{3} - 3 x^{2} + 10
