Based on the graph and the situation which domain and range make sense for function n?


A. Domain all numbers from 0 to 85. Range: all numbers from 0 to 14.

B. Domain whole numbers only from 0 to 14. Range: whole numbers only from 0 to 85.

C. Domain all numbers from 0 to 10. Range: whole numbers only from 0 to 50.

D. Domain whole numbers only from 0 to 10. Range : all numbers from 0 to 50.

The correct option is C.


Domain is all the values which lie on the x-axis, or the x values, and the range is all the values which lie on the y-axis, or the y values.


So, the hours since opening is the domain and the number of visitors is the range. The number of hours can be any number including decimal numbers, from 0 to 10 as shown in the graph, but the number of visitors cannot be a decimal number, so the range can only be whole numbers from 0 to 50.
