critical f(x)=(12-4x)e^x

critical points

f (x) = (12 - 4 x) e^{x}

x = 2

Solution steps

(12 - 4 x) e^{x}

Find where

f^{'} (x)

is equal to zero or undefined

x = 2

Identify critical points not in

f (x)

domain

Domain of

(12 - 4 x) e^{x} : - \infty < x < \infty

All critical points are in domain

x = 2

f (x) = - \frac{1}{x}

49 x + 64

y = (\frac{x}{a ^{2} - x ^{2}} - arcsin (\frac{x}{a}))

f (x) = (\frac{1}{5})^{x}

f (x) = x^{2} - 4 x + 10
