inverse of f(x)=(-5x+1)/(5x-2)

inverse

f (x) = \frac{- 5 x + 1}{5 x - 2}

\frac{1 + 2 x}{5 ( 1 + x )}

Solution steps

y = \frac{- 5 x + 1}{5 x - 2}

Replace

x

with

y

x = \frac{- 5 y + 1}{5 y - 2}

Solve for

y, x = \frac{- 5 y + 1}{5 y - 2}

\frac{1 + 2 x}{5 ( 1 + x )}

f (x) = lo g_{7} (x - 1)

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

12 x

f (x) = 9 x^{2} + 1

f (x) = 9 x^{2} + 8
