    Part A: What type of function, linear or exponential, can be used to describe the value of the investment after a fixed number of years using option 1 and option 2? Explain your answer. (2 points) Part B: Write one function for each option to describe the value of the investment f(n), in dollars, after n years. (4 points) Part C: Belinda wants to invest in an option that would help to increase her investment value by the greatest amount in 20 years. Will there be any significant difference in the value of Belinda's investment after 20 years if she uses option 2 over option 1? Explain your answer, and show the investment value after 20 years for each option. (4 points)

    Part A. Option 1 is an arithmetic or linear progression. The investment increases by $300 /year Option 2 is a geometric or exponential progression. The investment increases by 12% /year Part B. Option 1: f(n) = 1000 + 300n Option 2: f(n) = 1000 * 1.12^n Part C. Substitute 20 for n in the above equations. So Option 1 after 20 years gives 7000, and Option 2 after 20 years gives 9646.29 Belinda should choose Option 2

    The price of products may increase due to inflation and decrease due to depreciation. Derek 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) = 72(1.25)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:
