(choose chapter or problem)

The table shows the consumption (in trillions of Btus) of geothermal energy and wind energy in the United States from 2001 through 2009. (Source: U.S. Energy Information Administration) (a) Use a graphing utility to find a cubic model for the geothermal energy consumption data and a quadratic model for the wind energy consumption data. Let represent the year, with corresponding to 2001. (b) Use the graphing utility to graph the data and the two models in the same viewing window. (c) Use the graph from part (b) to approximate the point of intersection of the graphs of the models. Interpret your answer in the context of the problem. (d) Describe the behavior of each model. Do you think the models can accurately predict consumption of geothermal energy and wind energy in the United States for future years? Explain. (e) Use your schools library, the Internet, or some other reference source to research the advantages and disadvantages of using renewable energy
