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

inverse

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

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

Solution steps

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

Replace

x

with

y

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

Solve for

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

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

f (x) = - 10 t^{2} + 60 t + 10

f (x) = 3 lo g_{10} (x - 1)

arccos (\frac{11}{x})

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

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