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 must be one that can be effectively determineed by a quadratic, cubic, or quartic polynomial function. The following banding graph was prepare in the web page of the Los Angeles measure 1.gens the independent (x) variable The independent variable name (x) is classs 2. call the dependent (y) variable. The dependent variable name (y) is Change in California nonfarm employment 3.Make a data tabularize from the training in the graph by estimating coordinates for points on the graph.

Due to the g raph has up to trinity 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 need the starring(p) coefficient for the fashion model be tyrannical or veto? 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 remedy and n (degree) is greater then 2. 7.Use the regression analysis orchestrate on your graphing electronic computer to find a polynomial model for the data. Using the regression analysis feature in the gr aphing calculator TI-83, we obtained the fol! lowing the polynomial model f(x) = 0.016x4 - 130.17x3 + 3915127344x2 523356382x + 2.62*1011 8.Does the model you found uphold to your pilot light expectations. Did you alter the degree? If so, formulate 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...If you want to recover a full essay, order it on our website: BestEssayCheap.com
