rg.00 6: Exponential Functions Assignment Booklet 6 7. The population of a city has been growing exponentially. The table below shows the population every ten years, starting in 1950. Year 1950 1960 1970 1980 1990 2000 2010 Population 199 499 243 128 296 371 361 275 440 392 536 835 654 399 a. Find the exponential regression equation in the form P(t) = ab' , where P(t) is the population and t is the number of years since 1950 (1950 is year 0). Express the values of a and b to the nearest hundredth. (2 marks) P (f ) = 199472. 5 1 ( 1. 22) +
