inverse of f(x)=(-2x+5)/(-3x+9)

inverse

f (x) = \frac{- 2 x + 5}{- 3 x + 9}

\frac{5 - 9 x}{- 3 x + 2}

Solution steps

y = \frac{- 2 x + 5}{- 3 x + 9}

Replace

x

with

y

x = \frac{- 2 y + 5}{- 3 y + 9}

Solve for

y, x = \frac{- 2 y + 5}{- 3 y + 9}

\frac{5 - 9 x}{- 3 x + 2}

y = \frac{2 x + 2}{5 x - 3}

f (x) = arctan (x), 0 < x \leq 1

f (x) = \frac{1}{1} x - \frac{3}{4}

\frac{3}{x} + 2

25 mod 111
