inverse of f(x)=(x+1)/(x+8)

Solution

inverse

f (x) = \frac{x + 1}{x + 8}

Solution

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

Solution steps

y = \frac{x + 1}{x + 8}

Replace

x

with

y

x = \frac{y + 1}{y + 8}

Solve for

y, x = \frac{y + 1}{y + 8}

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

Popular Examples

inflection f(x)=x^4-2x^2+2 inflection points

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

intercepts of f(x)=2x^5+16x^4-6x^3-48x^2 intercepts

f (x) = 2 x^{5} + 16 x^{4} - 6 x^{3} - 48 x^{2}

asymptotes of f(x)=(x+sin(xpi))/(x+1)asymptotes

f (x) = \frac{x + sin ( x π )}{x + 1}

intercepts of f(x)=-x-1 intercepts

f (x) = - x - 1

inverse of (2x+3)/(x+1)inverse

\frac{2 x + 3}{x + 1}
