The manager of a store recorded the annual sales S (in thousands of dollars) of a product

Question:

The manager of a store recorded the annual sales S (in thousands of dollars) of a product over a period of 7 years, as shown in the table, where t is the time in years, with t = 8 corresponding to 2008.

(a) Use the regression capabilities of a graphing utility to find a model of the form S = at³ + bt² + ct + d for the data.

(b) Use a graphing utility to plot the data and graph the model.

(d) Do you think the model would be accurate for predicting future sales? Explain.
