critical f(x)= x/(x^2-25)

critical points

f (x) = \frac{x}{x ^{2} - 25}

None

Solution steps

\frac{x}{x ^{2} - 25}

Find where

f^{'} (x)

is equal to zero or undefined

x = - 5, x = 5

Identify critical points not in

f (x)

domain

Domain of

\frac{x}{x ^{2} - 25} : x < - 5 or - 5 < x < 5 or x > 5

\frac{x}{x ^{2} - 25}

is not defined at

x = - 5, x = 5

, therefore:

None

y = 2 x^{3} - x^{2} + 3

2 x + 7 y = 14

f (x) = \frac{9 x - 9}{8 x + 1}

6 x - 3

f (x) = 3 + 5 + x
