For the following exercises, consider this scenario: A town has an initial population of 75,000. It grows at a constant rate of 2,500 per year for 5 years. 13. Find the linear function that models the town's 14. Find a reasonable domain and range for the population P as a function of the year, t, where t is function P. the number of years since the model began. 15. If the function P is graphed, find and interpret the 16. If the function P is graphed, find and interpret the x-and y-intercepts. slope of the function. 17. When will the output reached 100,000? 18. What is the output in the year 12 years from the onset of the model? SECTION 2.3 SECTION EXERCISES 171 For the following exercises, consider this scenario: The weight of a newborn is 7.5 pounds. The baby gained one-half pound a month for its first year. 19. Find the linear function that models the baby's 20. Find a reasonable domain and range for the weight, W, as a function of the age of the baby, in function W. months, t. 21. If the function W is graphed, find and interpret the 22.
