It occurs to me that I may have misunderstood your question and that
you'd like to know if a command is available by default in a specific
Ubuntu release. In that case, please disregard my previous message.

====================

To check all releases for a package, you'd want to replace
PACKAGENAME with the package you're wondering about in this URL to
get a list of the releases that come with the specified package:

https://launchpad.net/ubuntu/+source/PACKAGENAME

Your example of bc would look like this:

https://launchpad.net/ubuntu/+source/bc

====================

This is another URL that does the same thing, but checks ubuntu.com
instead of launchpad.net, and you'd want to replace PACKAGENAME with
the package you're wondering about when using this one, too:

https://packages.ubuntu.com/search?keywords=PACKAGENAME

Your example of bc would look like this:

https://packages.ubuntu.com/search?keywords=bc

====================

To check a specific release for a package, you'd want to replace
RELEASENAME with its shortened Ubuntu release nickname and
PACKAGENAME with the package you're wondering about:

https://launchpad.net/ubuntu/RELEASENAME/+package/PACKAGENAME

Your example of bc in Ubuntu 16.04 (Xenial Xerus) would look like
this:

https://launchpad.net/ubuntu/xenial/+package/bc
