\[ x \in \mathbb{R} \]
since $ e^x $ is never negative, we can't get zero in the denominator

Answer 3

domain means the values of the function within which the function will exist.
here 1+e^x cannot be equal to zero.
1+e^x>0
e^(x)>-1

Answer 4

How do you usually type domains?

Answer 5

If you are not familiar with the notation, it just says x can be any number.
