inverse of f(x)=(x+2)/(x+8)

Solution

inverse

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

Solution

\frac{2 - 8 x}{x - 1}

Solution steps

y = \frac{x + 2}{x + 8}

Replace

x

with

y

x = \frac{y + 2}{y + 8}

Solve for

y, x = \frac{y + 2}{y + 8}

\frac{2 - 8 x}{x - 1}

Popular Examples

f (x) = \frac{1}{6 x ^{2} - x - 12}

domain of (4x+7)/(6x^2+13x-5)domain

\frac{4 x + 7}{6 x ^{2} + 13 x - 5}

domain of (3x-5)/(2-4x)domain

\frac{3 x - 5}{2 - 4 x}

inverse of f(x)=(5x+2)/7 inverse

f (x) = \frac{5 x + 2}{7}

inverse of f(x)=2x^4,x>= 0 inverse

f (x) = 2 x^{4}, x \geq 0
