critical f(x)=x^3+15x^2

critical points

f (x) = x^{3} + 15 x^{2}

x = - 10, x = 0

Solution steps

x^{3} + 15 x^{2}

Find where

f^{'} (x)

is equal to zero or undefined

x = - 10, x = 0

Identify critical points not in

f (x)

domain

Domain of

x^{3} + 15 x^{2} : - \infty < x < \infty

All critical points are in domain

x = - 10, x = 0

f (x) = ln (2 x)

\frac{x}{x ^{2} - 9}

f (x) = (x - 1)^{2}

f (x) = 2 x + 8

x^{2} - 5 x + 6
