inverse of f(x)=30-30e^{-ln(10)x}

inverse

f (x) = 30 - 30 \cdot e^{- l n (10) \cdot x}

- \frac{ln ( - \frac{x - 30}{30} )}{ln ( 10 )}

Solution steps

y = 30 - 30 e^{- l n (10) x}

Replace

x

with

y

x = 30 - 30 e^{- l n (10) y}

Solve for

y, x = 30 - 30 \cdot e^{- l n (10) \cdot y}

- \frac{ln ( - \frac{x - 30}{30} )}{ln ( 10 )}

f (x) = \frac{x}{3}

f (x) = - 2 (x + 1)

y = x^{2} - 2 x - 3

g (x) = 3 x - 1

f (x) = 7^{x} + 2
