critical f(x)=-2x^2+12x-20

critical points

f (x) = - 2 x^{2} + 12 x - 20

x = 3

Solution steps

- 2 x^{2} + 12 x - 20

Find where

f^{'} (x)

is equal to zero or undefined

x = 3

Identify critical points not in

f (x)

domain

Domain of

- 2 x^{2} + 12 x - 20 : - \infty < x < \infty

All critical points are in domain

x = 3

7 x + 5 y = 1

(\frac{5}{3}, - \frac{16}{9}), (- \frac{1}{3}, \frac{19}{9})

f (x) = - 3 cos (3 x)

f (x) = sin (e^{- t})

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