inverse of f(x)=log_{2}(x-4)

Solution

inverse

f (x) = lo g_{2} (x - 4)

Solution

2^{x} + 4

Solution steps

y = lo g_{2} (x - 4)

Replace

x

with

y

x = lo g_{2} (y - 4)

Solve for

y, x = lo g_{2} (y - 4)

2^{x} + 4

Popular Examples

domain of f(x)=xsqrt(x-6)domain

f (x) = x x - 6

domain of f(x)= 1/(9x)domain

f (x) = \frac{1}{9 x}

parity f(x)=cos(2x)parity

f (x) = cos (2 x)

slope ofintercept 2x+y=-2 slope intercept

2 x + y = - 2

extreme f(x)=(e^x-e^{-x})/6 extreme points

f (x) = \frac{e ^{x} - e ^{- x}}{6}
