Question

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 (number of years) 1 2 3 4
f(t) (price in dollars) 65 84.5 109.85 142.81

Answer 10

I have no idea about part A.
but what's the question for part B like whether it's a function or not?!

Answer 11

f(x) = 72(1.25)x
Is the price of product A increasing or decreasing and by what percentage per year?

Try graphing the function, you'll see the slope is positive, so meaning A is increasing each year not sure what the exact percentage is, im still working on it

Answer 12

so f(x) = 72(1.25)x is the answer to b

Answer 13

f(t) =
F(t) = price in $
t = # of years
Fit that into a function
it's actually simple...
