critical f(x)=x^3-75x

critical points

f (x) = x^{3} - 75 x

x = - 5, x = 5

Solution steps

x^{3} - 75 x

Find where

f^{'} (x)

is equal to zero or undefined

x = - 5, x = 5

Identify critical points not in

f (x)

domain

Domain of

x^{3} - 75 x : - \infty < x < \infty

All critical points are in domain

x = - 5, x = 5

(- 2 - 6) 0

f (x) = (x - 3) (x + 6)

sec (x) - csc (x)

f (x) = \frac{x + 5}{2}

(x^{2} - 4)^{4}
