Using function concepts, it is found that:
- A reasonable domain is: {0, 1, 2, 3, 4, 5, 6}.
- A reasonable range is: {27, 30, 33, 46, 39, 42, 45}
----------------------------
- The domain of a function is the set that contains all possible input values.
- The range of a function is the set that contains all possible output values.
- She has 6 tickets left to sell, so she can sell at most 6 more tickets, which means that the input of the function is an integer number which is at most 6, thus a reasonable domain is: {0, 1, 2, 3, 4, 5, 6}.
- For each ticket sold, she earns $3. She already has $27, and the most she can earn is 27 + 3(6) = $45. Thus, a reasonable range, which contains her possible earnings, is: {27, 30, 33, 46, 39, 42, 45}
