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!

  2. 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.

  3. However it would not include 51.473
    so 100 * entry is integer

  4. What am I thinking?

    The RANGE is the amount in the account.

    The DOMAIN is the date :)
