70. Population Growth The projected populations of California for the years 2015 to 2030 can be modeled by P = 34.706-0.00971 where P is the population (in millions) and / is the time (in years), with / = 15 corresponding to 2015. (Source: U.S Census Bureau) (a) Use a graphing utility to graph the function for the years 2015 through 2030. (b) Use the rable feature of a graphing utility to create a table of values for the same time period as in part (a). (c) According to the model, when will the population of California exceed 50 million
