critical f(x)=2x^3-27x^2+84x

critical points

f (x) = 2 x^{3} - 27 x^{2} + 84 x

x = 2, x = 7

Solution steps

2 x^{3} - 27 x^{2} + 84 x

Find where

f^{'} (x)

is equal to zero or undefined

x = 2, x = 7

Identify critical points not in

f (x)

domain

Domain of

2 x^{3} - 27 x^{2} + 84 x : - \infty < x < \infty

All critical points are in domain

x = 2, x = 7

2 x + 5 y + 10 = 0

f (x) = x^{2} - 2 x - 24

(\frac{25}{2} x + 15) - 1

x^{\frac{5}{3}}

f (x) = \frac{( x - 1 )}{8}
