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 ðŸ˜›

Given function:

y = 1/(1 + x) ; x â‰ -1

Inverse function:

x = 1/(1 + y)

1 + y = 1/x

y = 1/x â€“ 1

y = (1 â€“Â x)/x; x â‰ 0 (answer)

f(x) = 1+x

x = 1+y

y = x-1

f^-1(x) = x-1
