WebTherefore, f and g are inverses. This is just finding the inverse, and it should suffice as an answer. The other way to do it is just to show that f (g (x)) = x = 1 / ( (1 + x)/x - 1) Then from there it's just more algebra. I think the first way is less algebra. http://dl.uncw.edu/digilib/Mathematics/Algebra/mat111hb/functions/inverse/inverse.html bper torre gaia https://ticoniq.com
