Answer: option c: the domain is all integer values in the interval [0,9460]
the range is all multiples of 45.5 in the interval [0,430430]
Explanation:
1) It is said that the revenue is a funciton of the number of people in attendance.
2) So, the independent variable is the number of people in attendance, and the dependent variable is the revenue in $.
3) The domain is the set of numbers that the independent variable (input) can take; that is the number of people that the stadium is capable of seating. Then it is all the integer values in the interval [0, 9460].
4) The otuputs are calculated as 45.5 times the number of people in attendance, so they are all the integer values in the interval [0, 430.430]. That is the range.
