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

Solution

inverse

f (x) = \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}

Popular Examples

domain of f(x)=(1-6sqrt(x))/x domain

f (x) = \frac{1 - 6 x}{x}

inflection f(x)=x^{2/3}-3 inflection points

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

inverse of 7x+2 inverse

7 x + 2

domain of f(10)= 1/(sqrt(x-1))domain

f (10) = \frac{1}{x - 1}

inverse of f(x)=sqrt(5x+15)inverse

f (x) = 5 x + 15
