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

Solution

inverse

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

Solution

- \frac{4 x}{x - 1}

Solution steps

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

Replace

x

with

y

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

Solve for

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

- \frac{4 x}{x - 1}

Popular Examples

extreme f(x)=-2x^2-6x+20 extreme points

f (x) = - 2 x^{2} - 6 x + 20

domain of f(x)=2x^3-x^2+2x-1 domain

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

inflection f(x)=4x^3-5x^2+2x-1 inflection points

f (x) = 4 x^{3} - 5 x^{2} + 2 x - 1

range of 3x-8 range

3 x - 8

intercepts of f(x)=x^3-10x^2+29x-20 intercepts

f (x) = x^{3} - 10 x^{2} + 29 x - 20
