inverse of f(x)=(-8x-7)/(9x-9)

inverse

f (x) = \frac{- 8 x - 7}{9 x - 9}

\frac{- 7 + 9 x}{9 x + 8}

Solution steps

y = \frac{- 8 x - 7}{9 x - 9}

Replace

x

with

y

x = \frac{- 8 y - 7}{9 y - 9}

Solve for

y, x = \frac{- 8 y - 7}{9 y - 9}

\frac{- 7 + 9 x}{9 x + 8}

f (x) = 11 x^{2} - 2

f (x) = 11 x^{2} + 4

f (x) = \frac{x + 6}{x}

f (x) = 8 arcsin (4 x)

\frac{3 x - 1}{2 - x}
