Lyme Disease The numbers Nof confirmed cases of Lyme disease in Maryland from 2007 through 2014 are shown in the table, where t represents the year, with t=7corresponding to 2007. (a) Use a graphing utility to create a scatter plot of the data. (b) Use the regression feature of the graphing utility to find a quartic model for the data. (A quartic model has the form at4+bt3+ct2+dt+e,where a,b,c,d,and e are constant and t is variable.) Graph the model in the same viewing window as the scatter plot. (c) Use the model to create a table of estimated values of N.Compare the model with the original data. (d) Use synthetic division to confirm algebraically your estimated value for the year 2014.
