Step-by-step explanation:

Step-by-step explanation:

Part A

The function representing the amount f(x), in dollars, in account A after x years is is given as

f(x) = 10,125(1.83)^x

Looking at the function, the amount of money in account A increasing. The percentage by which the amount in account A is increasing is 83%

Part B

The table below showing the amount g(r), in dollars, of money in account B after r years is given as

r (number of years) 1 2 3 4

g(r) (amount in dollars) 9,638 18,794.10 36,648.50 71,464.58

The change between year 1 and year 2 is

18794.10 - 9638 = 9156.1

Percentage change

= 9156.1/9638 × 100 = 95%

The change between year 2 and year 3 is

36648.50 - 18794.10 = 17854.4

Percentage change

= 17854.4/18794.10 × 100 = 95%

So the the percentage by which the amount in account B is increasing is 95%

Therefore, Account B recorded a greater percentage change in amount of money over the previous year. This is because 95% is greater than 83%
