Homework Statement
Show that the functions f are one-to-one and calculate the inverse function.
Homework Equations
f(x)= x/(1+x) (It is the equation I am having trouble with)
The Attempt at a Solution
I know the solution is y= x/(1-x) But no idea how to solve it.
My attempt:
x(1+y)=y or x+xy=y
y+y=x/x
