inverse of f(x)=sqrt(((e^x-8))/(2-e^x))

inverse

f (x) = \frac{( e ^{x} - 8 )}{2 - e ^{x}}

ln (- \frac{- 8 - 2 x ^{2}}{x ^{2} + 1})

Solution steps

y = \frac{e ^{x} - 8}{2 - e ^{x}}

Replace

x

with

y

x = \frac{e ^{y} - 8}{2 - e ^{y}}

Solve for

y, x = \frac{e ^{y} - 8}{2 - e ^{y}}

ln (- \frac{- 8 - 2 x ^{2}}{x ^{2} + 1})
