inverse of f(x)=(x-3)/(x+4)

Solution

inverse

f (x) = \frac{x - 3}{x + 4}

Solution

\frac{- 3 - 4 x}{x - 1}

Solution steps

y = \frac{x - 3}{x + 4}

Replace

x

with

y

x = \frac{y - 3}{y + 4}

Solve for

y, x = \frac{y - 3}{y + 4}

\frac{- 3 - 4 x}{x - 1}

Popular Examples

domain of f(x)= 1/4 x-2 domain

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

parity f(-x)=(x^2+5)/x parity

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

f (x) = x^{2} - 5 x + 6

inflection (e^x-e^{-x})/9 inflection points

\frac{e ^{x} - e ^{- x}}{9}

asymptotes of f(x)=(-3x+15)/(x^2-5x)asymptotes

f (x) = \frac{- 3 x + 15}{x ^{2} - 5 x}
