inverse of f(x)=(5-e^{-x})/(5+e^{-x)}

inverse

f (x) = \frac{5 - e ^{- x}}{5 + e ^{- x}}

- ln (\frac{5 - 5 x}{x + 1})

Solution steps

y = \frac{5 - e ^{- x}}{5 + e ^{- x}}

Replace

x

with

y

x = \frac{5 - e ^{- y}}{5 + e ^{- y}}

Solve for

y, x = \frac{5 - e ^{- y}}{5 + e ^{- y}}

- ln (\frac{5 - 5 x}{x + 1})
