inverse of f(x)=(e^x)/(7+2e^x)

inverse

f (x) = \frac{e ^{x}}{7 + 2 e ^{x}}

ln (- \frac{7 x}{2 x - 1})

Solution steps

y = \frac{e ^{x}}{7 + 2 e ^{x}}

Replace

x

with

y

x = \frac{e ^{y}}{7 + 2 e ^{y}}

Solve for

y, x = \frac{e ^{y}}{7 + 2 e ^{y}}

ln (- \frac{7 x}{2 x - 1})

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

sin (\frac{π}{6})

y = 5 - 9 x

y = 7 x^{2} - 10

f (x) = \frac{1}{1000} (2 x - 1)^{3} + 10
