inflection ((e^x))/(8+e^x)

Solution

inflection points

\frac{( e ^{x} )}{8 + e ^{x}}

Solution

(3 ln (2), \frac{1}{2})

Solution steps

f^{''} (x) = \frac{8 e ^{x} ( - e ^{x} + 8 )}{( 8 + e ^{x} ) ^{3}}

Find intervals:

Concave Upward

: - \infty < x < 3 ln (2),

Concave Downward

: 3 ln (2) < x < \infty

Plug

x = 3 ln (2)

into

\frac{e ^{x}}{8 + e ^{x}} : \frac{1}{2}

(3 ln (2), \frac{1}{2})

inverse of f(x)=4+sqrt(4x-5)inverse

f (x) = 4 + 4 x - 5

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

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