How do I find the inverse?
f(x) = 1/1+x
f(x) = 1/1+x

So that y= 1 Divided by 1 + whatever your main X number is
So lets say X is 2
1 divided by 1 is ... well.. 1
so 1 + 2 = 3
Now just do this for the chart you are using and you will be good to go.
Also just a tip If you having a graphing calculator Press the y= button at the top insert whatever your x Equation is and then press 2nd and then Graph and find the numbers you need :P

Given function:
y = 1/(1 + x) ; x ≠ -1
Inverse function:
x = 1/(1 + y)
1 + y = 1/x
y = 1/x – 1
y = (1 – x)/x; x ≠ 0 (answer)
?
f(x) = 1+x
x = 1+y
y = x-1
f^-1(x) = x-1
