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)=((2x+8))/((x^2-x))domain

f (x) = \frac{( 2 x + 8 )}{( x ^{2} - x )}

inverse of f(x)= x/2 inverse

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

inverse of f(x)=(-12x+x)/4 inverse

f (x) = \frac{- 12 x + x}{4}

amplitude of f(x)=-2-sin(2x)amplitude
