inverse of f(x)=((7x-1))/(9x+8)

inverse

f (x) = \frac{( 7 x - 1 )}{9 x + 8}

\frac{- 1 - 8 x}{9 x - 7}

Solution steps

y = \frac{7 x - 1}{9 x + 8}

Replace

x

with

y

x = \frac{7 y - 1}{9 y + 8}

Solve for

y, x = \frac{7 y - 1}{9 y + 8}

\frac{- 1 - 8 x}{9 x - 7}

f (x) = 4 - 7 y

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

x + 2 - 2 x + 3

f (x) = 2^{x - 3} - 5, (4, 7)
