inverse of f(x)=20-20e^{-ln(10)x}

inverse

f (x) = 20 - 20 e^{- l n (10) x}

- \frac{ln ( - \frac{x - 20}{20} )}{ln ( 10 )}

Solution steps

y = 20 - 20 e^{- l n (10) x}

Replace

x

with

y

x = 20 - 20 e^{- l n (10) y}

Solve for

y, x = 20 - 20 e^{- l n (10) y}

- \frac{ln ( - \frac{x - 20}{20} )}{ln ( 10 )}

3 x^{3} - 1

- x^{3}

f (x) = 4 - 9 x

f (x) = ln (2 x - 5)

\frac{( 3 - 2 x )}{3 x + b}
