The population P (in millions) of Italy from 2003 through 2015 can be approximated by the model  P = 57.59e0.0051t,  where t represents the year, with  t = 3  corresponding to 2003. (a) According to the model, is the population of Italy increasing or decreasing? Explain. Because the coefficient of the model is  ---Select--- positive negative  , the population is  ---Select--- increasing decreasing  .   (c) Use the model to predict the populations of the country in 2021 and 2026. (Round your answers to three decimal places.) 2021                    million 2026                    million

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
