Project 1

College Algebra Project 2 Directions Find a avert interpret or line graph in a newspaper, in a magazine or on the Internet. This graph essential be one that can be effectively determineed by a quadratic, cubic, or quartic multinomial function. The following deflect graph was gear up in the web page of the Los Angeles propagation 1.gens the independent (x) variable The independent variable name (x) is classs 2. phone call the dependent (y) variable. The dependent variable name (y) is Change in California nonfarm employment 3.Make a data tabularize from the data in the graph by estimating coordinates for points on the graph.

Due to the graph has up to triplet round points the function type is a Quartic polynomial degree 4) with a equation as follows f(x) = ax4 + bx3 + cx2 + dx + e 6.Do you impart the starring(p) coefficient for the fashion model be tyrannical or banish? 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 right hand and n (degree) is greater then 2. 7.Use the regression analysis conceive on your graphing electronic computer to find a polynomial model for the data. Using the regression analysis feature in the graphing calcula tor TI-83, we obtained the following the pol! ynomial model f(x) = 0.016x4 - 130.17x3 + 3915127344x2 523356382x + 2.62*1011 8.Does the model you found digest to your pilot light expectations. Did you alter the degree? If so, develop 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.
