inverse of f(x)=32-20e^{-0.4x}

inverse

f (x) = 32 - 20 e^{- 0.4 x}

- \frac{ln ( - \frac{x - 32}{20} )}{0.4}

Solution steps

y = 32 - 20 e^{- 0.4 x}

Replace

x

with

y

x = 32 - 20 e^{- 0.4 y}

Solve for

y, x = 32 - 20 e^{- 0.4 y}

- \frac{ln ( - \frac{x - 32}{20} )}{0.4}

f (x) = 2 x^{2} + 24 x - 3

4 x^{2} - 25

g (x) = - 2 x

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

f (x) = \frac{3 x - 5}{2 x + 1}
