critical f(x)=20x^3+60x^2-80

critical points

f (x) = 20 x^{3} + 60 x^{2} - 80

x = - 2, x = 0

Solution steps

20 x^{3} + 60 x^{2} - 80

Find where

f^{'} (x)

is equal to zero or undefined

x = - 2, x = 0

Identify critical points not in

f (x)

domain

Domain of

20 x^{3} + 60 x^{2} - 80 : - \infty < x < \infty

All critical points are in domain

x = - 2, x = 0

- 2 x^{2} - 24 x - 54

f (x) = 4 x^{2}

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

f (x) = 1 - 5 x + 2

5 y = 2 x
