inverse of y=e^x-e^{-x}

inverse

y = e^{x} - e^{- x}

ln (\frac{x + x ^{2} + 4}{2}), ln (\frac{x - x ^{2} + 4}{2})

Solution steps

y = e^{x} - e^{- x}

Replace

x

with

y

x = e^{y} - e^{- y}

Solve for

y, x = e^{y} - e^{- y}

ln (\frac{x + x ^{2} + 4}{2}), ln (\frac{x - x ^{2} + 4}{2})

3 y = 4 x + 5

f (x) = 8 x - 5

- x^{2} - 3 x + 4

f (x) = \frac{11}{11 - x}

6 x + 1
