Answer:
Mathematical domain is all numbers, as all numbers can be multiplied by 4. However, this is not reasonable as negative lengths don't exist, so the reasonable domain would be all positive numbers.
In order for something to be a function, it cannot have an x-value repeated. Therefore, (1,0) cannot be a possible ordered pair because the function already has a point at x=1 (1,2).
