Question

Your class is participating in a fundraising competition at your school. You are selling Chick-Fil-A calendars for $10$10 each.The equation to represent the sale of calendars is =10y=10x where x is the number of calendars sold. If you were to create a table of values and graph this function, what would the domain and range be?

Answer 1

Since x is the number of calendars sold, then x must be greater than or equal to zero and an integer, therefore y is a positive multiple of 10.

Therefore the domain of the function consists of all x whole numbers.

The range of the function consists of all whole numbers that are a multiple of 10 and zero.

Answer:

Domain: All whole numbers.

Range: Whole numbers multiples of 10.
