critical f(x)=2x^3-9x^2-24x+20

critical points

f (x) = 2 x^{3} - 9 x^{2} - 24 x + 20

x = - 1, x = 4

Solution steps

2 x^{3} - 9 x^{2} - 24 x + 20

Find where

f^{'} (x)

is equal to zero or undefined

x = - 1, x = 4

Identify critical points not in

f (x)

domain

Domain of

2 x^{3} - 9 x^{2} - 24 x + 20 : - \infty < x < \infty

All critical points are in domain

x = - 1, x = 4

What is the critical f(x)=2x^3-9x^2-24x+20 ?
The critical f(x)=2x^3-9x^2-24x+20 is x=-1,x=4
