(2 points) house complete mailing address The relation (house, complete mailing address) is a function, but the relation (complete mailing address, house) is not. The relation (complete mailing address, house) is a function, but the relation (house, complete mailing address) is not. Both (house, complete mailing address) and (complete mailing address, house) are functions. Neither the relation (house, complete mailing address) nor the relation (complete mailing address, house) is a function.

Note that mailing address is unique, but houses are not, meaning that you can't have house A and house B both referencing the same address.
So, in order to have a valid function, any two points on the function cannot have the same x value that lands on different y.
With this property mentioned, it's clear to see that(house, address) is NOT a function; however, (address, house) is a function, since same x lands on multiple y values is a valid onto function. (a house that have multiple addresses)
