inflection (3-x)e^{-x}

Solution

inflection points

(3 - x) e^{- x}

Solution

(5, - \frac{2}{e ^{5}})

Solution steps

f^{''} (x) = - e^{- x} (x - 5)

Find intervals:

Concave Upward

: - \infty < x < 5,

Concave Downward

: 5 < x < \infty

Plug

x = 5

into

(3 - x) e^{- x} : - \frac{2}{e ^{5}}

(5, - \frac{2}{e ^{5}})

Popular Examples

range of y= 1/x range

y = \frac{1}{x}

inverse of f(x)=4x^3+5 inverse

f (x) = 4 x^{3} + 5

asymptotes of f(x)=(x+1)/(x^2+8x)asymptotes

f (x) = \frac{x + 1}{x ^{2} + 8 x}

inverse of f(x)=5x-9 inverse

f (x) = 5 x - 9

domain of (x+3)^5 domain

(x + 3)^{5}
