inverse of f(x)= 2/(x+4)

Solution

inverse

f (x) = \frac{2}{x + 4}

Solution

\frac{2}{x} - 4

Solution steps

y = \frac{2}{x + 4}

Replace

x

with

y

x = \frac{2}{y + 4}

Solve for

y, x = \frac{2}{y + 4}

\frac{2}{x} - 4

Popular Examples

asymptotes of f(x)=(3x^3-1)/(x^2-2x)asymptotes

f (x) = \frac{3 x ^{3} - 1}{x ^{2} - 2 x}

critical f(x)=4x^3-3x critical points

f (x) = 4 x^{3} - 3 x

domain of f(x)=(x-3)/(x^2+x-12)domain

f (x) = \frac{x - 3}{x ^{2} + x - 12}

domain of sqrt(x-2)domain

x - 2

monotone f(x)=x-4/(x^2)monotone intervals

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