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

inverse

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

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

Solution steps

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

Replace

x

with

y

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

Solve for

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

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

f (x) = \frac{2}{5} x + 6

f (x) = \frac{8}{1 + x ^{2}}

\frac{e ^{x}}{9 + 4 e ^{x}}

f (x) = - 4 x - 9
