Answer:
x ≥ 0
Step-by-step explanation:
The independent variable here is the number of people attending the wedding. Theoretically there can never be fewer than zero people, and the size of the event may be limited by the facilities, ability to feed the guests, and so on. Thus the domain of this function is "all integers zero or greater."
Symbolically, x ≥ 0.
