Hi Guys, i am new to this forums and my english is poor, but i will do my best.(adsbygoogle = window.adsbygoogle || []).push({});

I got stuck with this problem, i think it's quite easy, but i get the wrong answer

F(x) = ln(1+e^x)

1. Show that it has an inverse

2. What is the Range And the Domain of the inverse.

I really appreciate a good solution so i can learn from my mistakes.
