Project 1

College Algebra Project 2 Directions Find a avert graphical record or line graph in a newspaper, in a magazine or on the Internet. This graph mustiness be one that can be effectively determineed by a quadratic, cubic, or quartic multinomial function. The following measuring rod graph was plunge in the web page of the Los Angeles clock 1.gens the independent (x) variable The independent variable name (x) is classs 2. birdcall the dependent (y) variable. The dependent variable name (y) is Change in California nonfarm employment 3.Make a data tabularize from the info in the graph by estimating coordinates for points on the graph.

Due to the graph has up to tercet round points the function type is a Quartic multinomial degree 4) with a equation as follows f(x) = ax4 + bx3 + cx2 + dx + e 6.Do you gestate the starring(p) coefficient for the fashion model be tyrannical or damaging? Explain your expectation.

I expect that the leading coefficient for the model be positive due to the graph of f(x) rises both to the left and to the chastise and n (degree) is greater then 2. 7.Use the regression analysis urinate on your graphing electronic computer to find a polynomial model for the data. Using the regression analysis featu re in the graphing calculator TI-83, we obta! ined the following the polynomial model f(x) = 0.016x4 - 130.17x3 + 3915127344x2 523356382x + 2.62*1011 8.Does the model you found sanction to your pilot light expectations. Did you alter the degree? If so, let off 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.
