critical f(x)=-5x^3+15x+3

critical points

f (x) = - 5 x^{3} + 15 x + 3

x = - 1, x = 1

Solution steps

- 5 x^{3} + 15 x + 3

Find where

f^{'} (x)

is equal to zero or undefined

x = - 1, x = 1

Identify critical points not in

f (x)

domain

Domain of

- 5 x^{3} + 15 x + 3 : - \infty < x < \infty

All critical points are in domain

x = - 1, x = 1

y = \frac{4}{x}

f (x) = (x + 2)^{2} (x - 1)^{4}

x + 10

y + 3 = 2 (x - 2)

2 x + 3

What is the critical f(x)=-5x^3+15x+3 ?
The critical f(x)=-5x^3+15x+3 is x=-1,x=1
