extreme f(x)=(x^2-1/2)e^{-2x}

Solution

extreme points

f (x) = (x^{2} - \frac{1}{2}) e^{- 2 x}

Solution

Minimum (\frac{1 - 3}{2}, \frac{e ^{- 1 + 3} ( 1 - 3 )}{2}), Maximum (\frac{1 + 3}{2}, \frac{e ^{- 1 - 3} ( 1 + 3 )}{2})

Solution steps

f^{'} (x) = - 2 e^{- 2 x} (x^{2} - x - \frac{1}{2})

Find intervals:

Decreasing

: - \infty < x < \frac{- 3 + 1}{2},

Increasing

: \frac{- 3 + 1}{2} < x < \frac{1 + 3}{2},

Decreasing

: \frac{1 + 3}{2} < x < \infty

Plug

x = \frac{1 - 3}{2}

into

(x^{2} - \frac{1}{2}) e^{- 2 x} : \frac{e ^{- 1 + 3} ( 1 - 3 )}{2}

Minimum (\frac{1 - 3}{2}, \frac{e ^{- 1 + 3} ( 1 - 3 )}{2})

Plug

x = \frac{1 + 3}{2}

into

(x^{2} - \frac{1}{2}) e^{- 2 x} : \frac{e ^{- 1 - 3} ( 1 + 3 )}{2}

Maximum (\frac{1 + 3}{2}, \frac{e ^{- 1 - 3} ( 1 + 3 )}{2})

Minimum (\frac{1 - 3}{2}, \frac{e ^{- 1 + 3} ( 1 - 3 )}{2}), Maximum (\frac{1 + 3}{2}, \frac{e ^{- 1 - 3} ( 1 + 3 )}{2})
