(03.03 MC) A mаrine biоlоgist is studying the grоwth of а pаrticular species of fish. She writes the following equation to show the length of the fish, f(m), in cm, after m months: f(m) = 4(1.08)m Part A: When the marine biologist concluded her study, the length of the fish was approximately 6.86 cm. What is a reasonable domain to plot the growth function? (4 points) Part B: What does the y-intercept of the graph of the function f(m) represent? (2 points) Part C: What is the average rate of change of the function f(m) from m = 3 to m = 7, and what does it represent? (4 points)
(03.02, 03.03, 03.04 MC) The price оf prоducts mаy increаse due tо inflаtion and decrease due to depreciation. Marco is studying the change in the price of two products, A and B, over time. The price f(x), in dollars, of product A after x years is represented by the function below: f(x) = 0.69(1.03)x Part A: Is the price of product A increasing or decreasing and by what percentage per year? Justify your answer. (5 points) Part B: The table below shows the price f(t), in dollars, of product B after t years: t (number of years) 1 2 3 4 f(t) (price in dollars) 10,100 10,201 10,303.01 10,406.04 Which product recorded a greater percentage change in price over the previous year? Justify your answer. (5 points)
