Where's the Function?

1.http://www.calculatedriskblog.com/2013/10/hotels-occupancy-rate-tracking-pre.html

 This article is describing the rates of occupancy of hotel rooms during different times of the year. I thought this was an interesting take because when I think of occupancy rates I think it would more depend on the number of hotel rooms available. I also liked that this graph showed the different rates compared to other years-this way the graph was not too thrown off from the recent recession.  The graph represents a function because the one output is directly affected by one input . The changing weeks of the year make a difference on the occupancy rates for hotels. Therefor, the graph is also a mathematical model because the output is determined by the input.

This article describes how a majority of Americans now favor the legalization of pot. However, the relationship between being an American and favoring the legalization of pot is not a function because there are multiple outputs for the same input. Just because you are an American does not mean you believe pot should be legalized.

  1. jack,

    your first example is very good and interesting. you did a good job of explaining some of the mathematical details, however, remember that an output directly being affected by an input means that a relationship is a mathematical model. the criteria for being a function is that there is exactly one output for one input.

    your second example is interesting, however, if you are referring to the information in the first paragraph, the relationships are functions. the percents would be inputs and the different categories would be the outputs.

    good articles, otherwise.
