Iris wants to graph the invasive snail population to show the city council. Justify what the appropriate domain and range would be for the function f(x), what the y-intercept would be, and if the function is increasing or decreasing. F(x) = 150(1 + .5)x Let’s plug in some values for x! Earlier Iris mentioned that she observed the snail’s growth for 15 years. So we can graph the population of the snails for all 15 of those years using the exponential function we made earlier. Starting at year 0, and ending at year 15. F(0) = 150(1 + .5)0 F(0) = 150(1.5)0 F(0) = 150(1) F(0) = 150 This means that at year 0, or the beginning, the snail population was 150. Now all we have to do is the same thing for year 1 to year 15. These should be our results: F(0) = 150 F(1) = 225 F(2) = 337 F(3) = 506 F(4) = 759 F(5) = 1139 F(6) = 1708 F(7) = 2562 F(8) = 3844 F(9) = 5766 F(10) = 8649 F(11) = 12974 F(12) = 19461 F(13) = 29192 F(14) = 43789 F(15) = 65684 What those mean is after 15 years [f(15)], the population of invasive snails is 65, 684. Now that we know what these represent and their values we can start to set their ordered pairs and plot them on a coordinate plane. These are the ordered pairs: (0, 150) (1, 225) (2, 337) (3, 506) (4, 759) (5, 1139) (6, 1708) (7, 2562) (8, 3844) (9, 5766) (10, 8649) (11, 12974) (12, 19461) (13, 29192) (14, 43789) (15, 65684) The domain for this function would be 0≤x≤15 and the range for this function is 150≤y≤65684. The y-intercept of this function is…
