Part A:
4: Twitter has increased 73% since its IPO. Originally it was $45.10, and now the prices for stock are much larger. 70 million shares have been sold. The function raises at a rate of 73%, and one could look up the prices for each day since the IPO last month, creating a function (one input for every output)
5: Non-linear
6: NA
7: Non-linear function because the rising (and falling) of the stock price doesn't increase at a constant rate. It goes up and down, making a non-linear
8: Yes because outputs depend on inputs.
PART B:
2: This article discusses how in the new age of technology, there are more whistlehackers. http://news.yahoo.com/2013-whistlehackers-214901268.html
3: The fact that there is this technology doesn't necessarily mean that there will be more whistlehackers. They are related, but the whistlehacker quantity doesn't depend on the quantity of technology available
4: Its not a function, because there could be multiple outputs for the amount of inputs.
Very good job Nicole!
ReplyDeleteGreat job Nicole such an interesting topic
ReplyDeleteI like how you used the current event of Twitter's IPO for this activity! Good application to business
ReplyDeleteI used to have a twitter so I can relate to this ! interesting article !
ReplyDeletenicole,
ReplyDeletegood, very interesting and relevant to everyone on your first article. i don't have a twitter account, but i know it's popular and i should probably by stock in it. just to clarify, you are saying that the input values are days and that they output values are prices? if that is the case, i don't think that this relationship constitutes a mathematical model basically based on the explanation that you gave for why it is not linear.
your second example is a super interesting hot topic! you don't explain which quantities would be inputs and outputs, so i can't really assess whether there would be multiple outputs for inputs. if technology is an input quantity and whistle hacker is the output, then the relationship is a function, not an example of a non-function.
