inverse of f(x)=(9x)/(x+1)

Solution

inverse

f (x) = \frac{9 x}{x + 1}

Solution

- \frac{x}{x - 9}

Solution steps

y = \frac{9 x}{x + 1}

Replace

x

with

y

x = \frac{9 y}{y + 1}

Solve for

y, x = \frac{9 y}{y + 1}

- \frac{x}{x - 9}

Popular Examples

domain of f(x)=5x+1 domain

f (x) = 5 x + 1

domain of f(x)=2x^2-x+4 domain

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

inflection f(x)=(x^2)/(7x^2+8)inflection points

f (x) = \frac{x ^{2}}{7 x ^{2} + 8}

perpendicular y=7x-1 perpendicular

y = 7 x - 1

critical x^4-x^3-6x^2-2x-1 critical points

x^{4} - x^{3} - 6 x^{2} - 2 x - 1
