What's Your Function?- Post 2

Part A
http://money.cnn.com/2014/01/16/technology/apple-china-mobile/index.html
This article is about the beginning of the sale of iPhones on the China mobile phone market. The relationship between the sale of the iPhone and the success of the Chinese branch of Apple represent a functional relationship because specific numbers of iPhones sold will lead to profit for the company. Each input (the amount of phones sold) will result in only 1 output (the company's profit). This is not a linear function because there is no way to control exactly how many phones are sold each month or year, therefore the average rate of change is not constant. This relationship is a mathematical model because the output depends on the input.
profit = f(phones sold)
Part B

This article discusses the fact that the consumption of tobacco (the input) has been proven to lead to more and more illnesses (the output) than scientists were previously aware of. This relationship is not a function because there is not one output for every input as a smoker can have a variety of diseases or none at all.
Very interesting articles!
ReplyDeleteI had an article like yours. Cool.
ReplyDeleteI really like your example for part B, because its os not easy to find an article that shows a non function relationship. It is also a relevant topic so good job.
ReplyDeleteI liked your post! Those were very interesting articles. I found myself thinking more deeply about the issues that tobacco use has caused.
ReplyDeleteemily,
ReplyDeletewonderful job on your first example! you explained everything in great detail. i especially like how you used the appropriate math language to explain your reasoning behind mathematical models for this example.
since the article that you chose does not give any organized information like amount of consumption or consumption by year, etc., yes, i think you are correct in saying that the relationship is an example of a non function. nice job!
