f(x)=2xe^{-x}-x^2e^{-x}

Solution

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

Solution

Domain : - \infty < x < \infty

Range : f (x) \leq - 2 e^{- 2 + 2} + 22 e^{- 2 + 2}

X Intercepts : (0, 0), (2, 0), Y Intercepts : (0, 0)

Asymptotes : Horizontal y = 0

Extreme Points : Maximum (2 - 2, - 2 e^{- 2 + 2} + 22 e^{- 2 + 2}), Minimum (2 + 2, - 2 e^{- 2 - 2} - 22 e^{- 2 - 2})
