A function is created to represent the amount of money in your checking account. What restrictions would be made to the domain?

-The domain would include all real numbers.*
-The domain would only include positive integers.
-The domain would only include positive numbers.
-The domain would only include integers.

I am thinking that it could also be negative.

Thank you for any and all help!

Changing my mind. It is D.
Why would it be integers?
$ 51.47 for example

I suppose it could be negative if your bank has some sort of policy covering your bad checks.
However it would not include 51.473
so 100 * entry is integer
What am I thinking?

The RANGE is the amount in the account.

The DOMAIN is the date :)
