Kameron Shea · Answer 1

Functions will not have repeating x values ... they can have repeating y values, just not the x ones.

so both A and B are functions ... because all the x values are different

Serenity Guzman · Answer 2

Both. As long as the x inputs have different y outputs, it will always be a function.
