I believe you meant
1. f%28x%29=e%5E%28x%2B2%29
2. f%28x%29=e%5Ex+%2B2
Both functions are related to g%28x%29=e%5Ex
e%5Ex exist for any real value of the exponent,
so there are no restrictions to the domain of the functions;
they are defined for all real numbers.
The domain is all the real numbers.

g%28x%29=e%5Ex%3E0 Its range is the positive real numbers.
The same goes for f%28x%29=e%5E%28x%2B2%29
e%5Ex%3E0 --> e%5Ex%2B2%3E2
So, the range of f%28x%29=e%5Ex+%2B2 are the real numbers greater than 2.
