Final answer:
The domain of the function is x and the range is y = 2x, 0 ≤ y ≤ 514.
Step-by-step explanation:
The function represents the number of boxes of candy sold by Cameron in terms of the price of each box of candy. Let's call the number of boxes of candy sold as 'x' and the price per box as 'y'. The domain of the function is the set of possible values for 'x'. Since Cameron is trying to sell a maximum of 257 boxes of candy, the domain of the function is 0 ≤ x ≤ 257. The range of the function is the set of possible values for 'y'. Since each box of candy is $2, the range of the function is y = 2x, 0 ≤ y ≤ 514.
