The table given below shows the Consumer Price Index (CPI) for selected years. Use the regression capabilities of a graphing utility to find a mathematical model of the form y = at² + bt+c for the data. In the model, y represents the CPI and t represents the year, with t=5 corresponding to 1975. Round all numerical values in your answer to three decimal places.

Transcribed Image Text:The table given below shows the Consumer Price Index (CPI) for selected years. Use the regression
capabilities of a graphing utility to find a mathematical model of the form y = at² + bt+c for the data.
In the model, y represents the CPI and t represents the year, with t = 5 corresponding to 1975. Round all
numerical values in your answer to three decimal places.
