C. because the decimal is never ending, so it is irrational.
Since each stapler costs 16.99, the total cost is 16.99*x, with x representing the number of staplers bought. This works due to that he adds 16.99 for every stapler, and multiplying it adds 16.99 each time he buys a new stapler

Hello! Remember you have to write complete questions in order to get good and exact answers. Here you forgot to write the relation so I could help you providing my own relation.
Remember that for any relation, we have a set 
that matches the the domain (also called the set of inputs) of the function and the set 
that contains the range (also called the set of outputs).
Suppose our relation is:
So the x-values represents the set A and the y-values the set B. Therefore, by evaluating the x-values into our relation we get:
So in this context, the correct option is:
B) (-9,-8, -7, -6, -5}
