extreme y=-2x^2e^{-2x}-2

extreme

Maximum (0, - 2), Minimum (1, - \frac{2}{e ^{2}} - 2)

Solution steps

f^{'} (x) = 4 e^{- 2 x} x (x - 1)

Find intervals:

Increasing

: - \infty < x < 0,

Decreasing

: 0 < x < 1,

Increasing

: 1 < x < \infty

Plug

x = 0

into

- 2 x^{2} e^{- 2 x} - 2 : - 2

Maximum (0, - 2)

Plug

x = 1

into

- 2 x^{2} e^{- 2 x} - 2 : - \frac{2}{e ^{2}} - 2

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

Maximum (0, - 2), Minimum (1, - \frac{2}{e ^{2}} - 2)
