inverse of f(x)=(3x)/(x+4)

Solution

inverse

f (x) = \frac{3 x}{x + 4}

Solution

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

Solution steps

y = \frac{3 x}{x + 4}

Replace

x

with

y

x = \frac{3 y}{y + 4}

Solve for

y, x = \frac{3 y}{y + 4}

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

Popular Examples

inverse of f(x)=7x^7 inverse

f (x) = 7 x^{7}

intercepts of f(x)=(x+10)/(x-4)intercepts

f (x) = \frac{x + 10}{x - 4}

extreme f(x)=4x-2x^3-5 extreme points

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

range of sqrt(x^2-10)range

x^{2} - 10

domain of f(x)=-ax domain

f (x) = - a x
