inverse of f(x)=(x+1)/(2x+1)

Solution

inverse

f (x) = \frac{x + 1}{2 x + 1}

Solution

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

Solution steps

y = \frac{x + 1}{2 x + 1}

Replace

x

with

y

x = \frac{y + 1}{2 y + 1}

Solve for

y, x = \frac{y + 1}{2 y + 1}

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

Popular Examples

range of f(x)=2x^2+4 range

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

extreme f(x)=-2x^2-16x-25 extreme points

f (x) = - 2 x^{2} - 16 x - 25

critical f(x)=x^3-x^2+3 critical points

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

inverse of f(x)=(x+2) 1/5 inverse

f (x) = (x + 2) \frac{1}{5}
