critical x^3-9x^2+15x+25

critical points

x^{3} - 9 x^{2} + 15 x + 25

x = 1, x = 5

Solution steps

x^{3} - 9 x^{2} + 15 x + 25

Find where

f^{'} (x)

is equal to zero or undefined

x = 1, x = 5

Identify critical points not in

f (x)

domain

Domain of

x^{3} - 9 x^{2} + 15 x + 25 : - \infty < x < \infty

All critical points are in domain

x = 1, x = 5

f (x) = \frac{( x ^{2} - 25 )}{5 x - 9}

y = e^{x}

\frac{4 x ^{2} - 4}{x + 4}

f (x) = 3 tan (9 x)

f (x) = x^{2} - 3
