Article: "Income is on the rise... finally!" by CNN Money
-Article discusses the increase of median household income over the past few years.
Part A:
- The graph is a function due to each input value (year) having exactly one input value (median household income), it also passed the vertical line test.
- For every year, there is exactly one median household income.
- The graph is not a linear function because there is not a constant average rate of change , or slope, between values.
- This function is not a mathematical model because the output, in this case the median household income, does not depend on the input, the year.
Part B:
Article: "Where cuts hurt most" by Brad Edmondson, published in American Demographics
-Article analyzes each states education and health care dependency rates for children and the elderly.
Link: http://search.proquest.com/docview/200533731/fulltextPDF?accountid=8285- In the scatterplot for every output, ( the population under age 18 or population of elderly 65 or older), there are more than one in some cases, input ( states).
- This relationship is not a graph because it does not pass the vertical line test, also more than one input corresponds to one output.
Bianca,
ReplyDeleteI really liked that you picked articles that many people can relate too. Furthermore, I liked that I am now able to take the valuable information that you described an apply that to not only MATH, but other course too.

I agree with Tyler. I think this graph is easy to read and understand as well. It is also very relatable to many.
ReplyDeleteI like how your graph for part a is easy to understand. The data is displayed in an accessible and straightforward way.
ReplyDeletebianca,
ReplyDeleteyour first example is good and very accessible. your explanations are well done. however, you forgot to represent the relationship using function notation.
i could not open the link for your second example, so i am unable to assess your work there.
