Find a third-degree-polynomial model of salinity as a function of time . Use the general form of a polynomial in the box on page 114 of our textbook. Hint: proceed much as you did for the quadratic model, and look ahead to the next paragraph.
Explain why it’s possible to find more than one third-degree-polynomial model that fits the data perfectly.
Use your third-degree-polynomial model to predict the salinity at .
Make a large graph of your third-degree-polynomial model, at least through .
Use your third-degree-polynomial model to predict the long-term trend of salinity.
