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

Solution

inverse

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

Solution

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

Solution steps

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

Replace

x

with

y

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

Solve for

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

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

inverse of f(x)=5x-10 inverse

f (x) = 5 x - 10

domain of f(x)= 4/(x-1)+3 domain

f (x) = \frac{4}{x - 1} + 3

inverse of f(x)=225+0.3x inverse

f (x) = 225 + 0.3 x
