critical f(x)=ln(x-3)

critical points

f (x) = ln (x - 3)

None

Solution steps

ln (x - 3)

Find where

f^{'} (x)

is equal to zero or undefined

x = 3

Identify critical points not in

f (x)

domain

Domain of

ln (x - 3) : x > 3

ln (x - 3)

is not defined at

x = 3

, therefore:

None

- x^{2} + 4 x - 4

f (x) = 3 x - y = 9

f (x) = - x + 3 y = - 2

lo g_{10} (x^{2} - 1)

f (x) = \frac{x + 9}{x ^{2} - 9}
