inverse of f(x)=(x-1)/(x+4)

Solution

inverse

f (x) = \frac{x - 1}{x + 4}

Solution

\frac{- 1 - 4 x}{x - 1}

Solution steps

y = \frac{x - 1}{x + 4}

Replace

x

with

y

x = \frac{y - 1}{y + 4}

Solve for

y, x = \frac{y - 1}{y + 4}

\frac{- 1 - 4 x}{x - 1}

Popular Examples

domain of f(x)=(x^2)/(4x-5)domain

f (x) = \frac{x ^{2}}{4 x - 5}

asymptotes of f(x)=2x+3=0 asymptotes

f (x) = 2 x + 3 = 0

asymptotes of f(x)= 1/2*4^x asymptotes

f (x) = \frac{1}{2} \cdot 4^{x}

inverse of f(x)=sqrt((x-3)/3)+1 inverse

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

asymptotes of f(x)=(x^2+4x-5)/(x^2-9)asymptotes

f (x) = \frac{x ^{2} + 4 x - 5}{x ^{2} - 9}
