College Algebra Project 2 Directions Find a bar graph or line graph in a newspaper, in a magazine or on the Internet. This graph must be one that can be effectively modeled by a quadratic, cubic, or quartic polynomial function. The following bar graph was found in the web page of the Los Angeles Times 1. Name the independent (x) variable The independent variable name (x) is “Years” 2. Name the dependent (y) variable. The dependent variable name (y) is “Change in California nonfarm employment” 3. Make a data table from the information in the graph by estimating coordinates for points on the graph. Year 2000 2001 2002 2003 2004 2005 2006 2007 2008 Change in California nonfarm Employment 3.6 0.8 -1.0 -0.5…show more content…
Does the model you found confirm to your original expectations. Did you alter the degree? If so, explain why you made the change. Yes, the model that I found confirm to my original expectations. I did not alter the degree. 9. Comment of the validity of your model. Do you believe it would be useful for making future predictions? Why or why not? My model is valid due to the values of the independent (x) and dependent (y) variables are included. However, I do not believe that the model is useful to make future predictions because the variable (y) “Change in California nonfarm employment” could vary at any time either upward or downward depending on different factors (economic policy, etc). 10. Write two questions about the data that can be answered by using the model you generated in question 7. a) What years the California nonfarm employment did not have changes? b) How many times the changes in the Califonia nonfarm employment was 1% between 2000 and 2007 and what years? 11. Answer the questions in #10, showing how you used the model in your solution. a) The California nonfarm employment did not have changes between 2001 and 2002 and between 2003 and
