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

critical points

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

x = - 2, x = 0

Solution steps

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

Find where

f^{'} (x)

is equal to zero or undefined

x = - 2, x = 0

Identify critical points not in

f (x)

domain

Domain of

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

All critical points are in domain

x = - 2, x = 0

9 x^{2} - 16

f (x) = \frac{5 t - 1}{t ^{3} - t ^{2} - 8 t}

f (x) = 8 x^{3} - 12 x^{2} + 4

(5 - x)^{4}
