Best ResponseYou've already chosen the best response.0The 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 Which product recorded a greater percentage change in price over the previous year? Justify your answer. (5 points)

Best ResponseYou've already chosen the best response.1the general form of a growth/decay exponential function is f(x) = a(r)^x our function is f(x) = 72(1.25)^x can you tell me what r = ?

Best ResponseYou've already chosen the best response.1f(x) = a(r)^x f(x) = 72(1.25)^x r = ?

Best ResponseYou've already chosen the best response.1look at the underlined parts can you tell me what r = ?

Vocaloid

Best ResponseYou've already chosen the best response.1right, r = 1.25 the value of r tells us whether the function is increasing or decreasing if r > 1, our function is increasing if r < 1, our function is decreasing is our function increasing or decreasing?

Vocaloid

Best ResponseYou've already chosen the best response.1right, increasing now we need to find the percentage if r = 1.25 = 1 + (percentage/100), what is our percentage?

Vocaloid

Best ResponseYou've already chosen the best response.1right, 0.25 is the number I was trying to get at earlier, haha 0.25 (which is also equal to 25%) represents the percent increase per year

Best ResponseYou've already chosen the best response.1"Part A: is the price of product A increasing or decreasing and by what percentage per year?"

Vocaloid

Best ResponseYou've already chosen the best response.1right, and what percentage?

Vocaloid

Best ResponseYou've already chosen the best response.1right now are you ready to move to part B?

Vocaloid

Best ResponseYou've already chosen the best response.1alright, to find the percent increase for part B, we need to calculate the ratio f(2)/f(1) looking at the table, we know that f(2) = 84.5 f(1) = 64 f(2)/f(1) = ?

Vocaloid

Best ResponseYou've already chosen the best response.1right! this gives our r value, 1.3 so, r = 1.3 now we need to find the percent increase 1.3 = 1 + (increase) what is the value of (increase)?

Vocaloid

Best ResponseYou've already chosen the best response.1yes! so, our increase is 0.3, which is the same as 30%
