inverse of f(x)=(x+2)/(9x+7)

inverse

f (x) = \frac{x + 2}{9 x + 7}

\frac{2 - 7 x}{9 x - 1}

Solution steps

y = \frac{x + 2}{9 x + 7}

Replace

x

with

y

x = \frac{y + 2}{9 y + 7}

Solve for

y, x = \frac{y + 2}{9 y + 7}

\frac{2 - 7 x}{9 x - 1}

f (x) = - 2 x + 1 - 4

[3122]

- 4 + x^{2} - 2 x + 17

f (x) = \frac{e ^{x}}{1 + 2 e}

y = 5 x - 9
