What's Your Function?
Part A:
2. The relationship for function is when each input has one output
3. The data above
4. It shows that as the year increases the revenue of the Coca Cola Company also increases
5. This is not a linear function
6. -
7. This is because it doesn't have the constant rate of change. If we find the change of 2009 -2010 and 2011-2010, the change will not be the same.
8. It's not a mathematical model because the input doesn't depend on output
Part B
For part B I found a chart of Princeton's acceptance- the GPA, SAT and ACT scores
http://collegeapps.about.com/od/GPA-SAT-ACT-Graphs/ss/princeton-admission-gpa-sat-act.htm
1. Relationships that are not functions is when inputs have many outputs
2.
3. From the graph there are more inputs for one output ( There are many students who has the same score of SAT/ACT scores and GPA
4. This is not a function because there are multiple outputs for one input
Hi Ance, I agree with your opinion that part B is not a function because there are lots of inputs match with one outputs.
ReplyDeleteInteresting articles! And I agree with your analysis.
ReplyDeleteWow, I had no idea that Coca-Cola had increased its profits in such a significant way. Interesting choice!
ReplyDeleteance,
ReplyDeletenice job on both of these examples. your second graph is clearly a non function. in the explanations for your first example, you defined function incorrectly. it is that one output has exactly one input and not visa versa. additionally, you forgot to express the relationship using function notation. other than this, overall good job.

ance,
ReplyDeletethe post was also one day late, so it will lose a point.
