inverse of f(x)=(9x)/(x+9)

Solution

inverse

f (x) = \frac{9 x}{x + 9}

Solution

- \frac{9 x}{x - 9}

Solution steps

y = \frac{9 x}{x + 9}

Replace

x

with

y

x = \frac{9 y}{y + 9}

Solve for

y, x = \frac{9 y}{y + 9}

- \frac{9 x}{x - 9}

Popular Examples

domain of f(x)=sqrt(x^2+5x-6)domain

f (x) = x^{2} + 5 x - 6

domain of (x^2+3)/(x^2-2x-3)domain

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

range of f(x)=-2x+4 range

f (x) = - 2 x + 4

domain of f(x)= 7/(x-3)domain

f (x) = \frac{7}{x - 3}

range of f(x)=2^{-x}-4 range

f (x) = 2^{- x} - 4
