inverse of f(x)=4*5^x

Solution

inverse

f (x) = 4 \cdot 5^{x}

Solution

\frac{ln ( \frac{x}{4} )}{ln ( 5 )}

Solution steps

y = 4 \cdot 5^{x}

Replace

x

with

y

x = 4 \cdot 5^{y}

Solve for

y, x = 4 \cdot 5^{y}

\frac{ln ( \frac{x}{4} )}{ln ( 5 )}

Popular Examples

f (x) = 2 x + 2

perpendicular x+2y=0,(1,2)perpendicular

x + 2 y = 0, (1, 2)

asymptotes of f(x)=(1+e^{-x})/(3e^x)asymptotes

f (x) = \frac{1 + e ^{- x}}{3 e ^{x}}

inverse of f(x)= x/(2-x)inverse

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

domain of 4x^2-8x+2 domain

4 x^{2} - 8 x + 2
