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:
t (# in years) 1 2 3 4
f(t) ($ in dollars) 65 84.5 109.85 142.81

Best ResponseYou've already chosen the best response.0I suspect the function should be written: \(f(x) = 72(1.25)^x\) Whenever there is an exponent, write the ^ sign before it so helpers know that the number is exponentiated and not multiplied. It is perfectly ok to write f(x) = 72(1.25)^x which means the same function.
