critical y=9x^2-x^3-3

critical points

y = 9 x^{2} - x^{3} - 3

x = 0, x = 6

Solution steps

9 x^{2} - x^{3} - 3

Find where

f^{'} (x)

is equal to zero or undefined

x = 0, x = 6

Identify critical points not in

f (x)

domain

Domain of

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

All critical points are in domain

x = 0, x = 6
