inverse of f(x)=(x-11)/(x+9)

inverse

f (x) = \frac{x - 11}{x + 9}

\frac{- 11 - 9 x}{x - 1}

Solution steps

y = \frac{x - 11}{x + 9}

Replace

x

with

y

x = \frac{y - 11}{y + 9}

Solve for

y, x = \frac{y - 11}{y + 9}

\frac{- 11 - 9 x}{x - 1}

e^{2 - x}

f (x) = - 6 + x

- 4 - j^{6}

f (x) = \frac{1}{3 x + 5}

y = 5 x - 15
