inverse of f(x)=(100000)/(100+900e^{-t)}

inverse

f (x) = \frac{100000}{100 + 900 e ^{- t}}

- ln (\frac{1000 - t}{9 t})

Solution steps

x = \frac{100000}{100 + 900 e ^{- t}}

Replace

t

with

x

t = \frac{100000}{100 + 900 e ^{- x}}

Solve for

x, t = \frac{100000}{100 + 900 e ^{- x}}

- ln (\frac{1000 - t}{9 t})
