Each group member should consult an almanac, newspaper, magazine, or the Internet to find data that initially increase and then decrease, or vice versa, and therefore can be modeled by a quadratic function. Group members should select the two sets of data that are most interesting and relevant. For each data set selected,
a. Use the quadratic regression feature of a graphing utility to find the quadratic function that best fits the data.
b. Use the equation of the quadratic function to make a prediction from the data. What circumstances might affect the accuracy of your prediction?
c. Use the equation of the quadratic function to write and solve a problem involving maximizing or minimizing the function.
