critical 9xln(x)

Solution

critical points

9 x ln (x)

Solution

x = \frac{1}{e}

Solution steps

9 x ln (x)

Find where

f^{'} (x)

is equal to zero or undefined

x = \frac{1}{e}, x = 0

Identify critical points not in

f (x)

domain

Domain of

9 x ln (x) : x > 0

9 x ln (x)

is not defined at

x = 0

, therefore:

x = \frac{1}{e}

Popular Examples

critical f(x)=5x^2sqrt(x+1)critical points

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

critical f(x)=(3x^2)/(x^2+25)critical points

f (x) = \frac{3 x ^{2}}{x ^{2} + 25}

critical f(x)=9x^2+2y^2-xy^2 critical points

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

critical f(x)=4x^{1/3}-8x^{4/3}critical points

f (x) = 4 x^{\frac{1}{3}} - 8 x^{\frac{4}{3}}

critical 4xsqrt(100-x^2)critical points

4 x 100 - x^{2}
