A function has a one to one pair relation ship from the domain to the range, unlike any old random relation. That should answer part of number 1

The domain of a function is all the numbers of a function which can be inputted into it for an answer- The range is all the numbers which are a product- the end result of those numbers put into the function. That  should answer part of number 2
