Part A: The amount of money is increasing by 83% per year.

Part B: 95%

The function g(r) recorded the greatest percent change

Step-by-step explanation:

Assuming

Part A;

For the function   the percentage change is found by taking the slope between two consecutive points of the function and then seeing how it compares to the original amount

which is the amount increase per year. The percent this is of the original amount is

thus, the amount of money is increasing by 83% per year.

Part B:

The table gives shows us that the function is not linear, because there is no constant slope between the consecutive points, for example

and so on.

Now, let us find the percentage increase between the amount of money in consecutive years:  

we clearly see here that percent increase is 95%.

Since the function g(r) has greater percent increase than f(x), we conclude that g(r) recorded the greatest percent change over the previous year.
