A vacation home in Orlando, Florida, rents for $105 per day. The function gives the cost of renting the home for x days. What is the domain of this function? A.{0,1,2,3,...}
B. all real numbers
C.{0,105,210,315, ...}
D. x≥0

A.

Step-by-step explanation:

The domain has to be a number of days, counted using whole numbers.  It might be tempting to choose answer D, but that set includes numbers like 3.1416.  Really?  I want to rent a vacation home for 3.1416 days?  :-)

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
