critical x^4-12x^3

critical points

x^{4} - 12 x^{3}

x = 0, x = 9

Solution steps

x^{4} - 12 x^{3}

Find where

f^{'} (x)

is equal to zero or undefined

x = 0, x = 9

Identify critical points not in

f (x)

domain

Domain of

x^{4} - 12 x^{3} : - \infty < x < \infty

All critical points are in domain

x = 0, x = 9

y = 2 x^{2} - 5

f (x) = \frac{3 x - 2}{2 x + 1}

3 x + 2

4 x + 6 y = - 84

f (x) = x 25 - x^{2}
