Final answer:
To predict the population of Arizona for any year, you can use regression analysis to find an exponential model. The model will be in the form y = ab^x, where y is the predicted population, a is a constant coefficient, b is the base of the exponential term, and x is the year.
Step-by-step explanation:
To find the exponential model that could be used to predict the population of Arizona for any year (x), we need to use regression analysis. The regression equation will represent the relationship between the year and the population. We can use software or a graphing calculator to perform the regression analysis and obtain the exponential model. The resulting equation will be in the form y = ab^x, where y is the predicted population, a is a constant coefficient, b is the base of the exponential term, and x is the year.
