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

inflection

Solution steps

Find where

f^{''} (x)

is equal to zero or undefined

Identify inflection points not in domain or where

f (x)

is not continuous

Domain of

e^{- x^{3}} : - \infty < x < \infty

All inflection points are in domain and not on domain edges

Find intervals:

Concave Upward

: - \infty < x < 0,

Concave Downward

Concave Upward

Plug

x = 0

into

e^{- x^{3}} : 1

(0, 1)

Plug

into

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