What is the equation of line l? y = -x - 1 y = x + 1 y = 3x - 3 y = -3x - 3

Step-by-step explanation:

Part A

The function representing the amount of money in account A after x years is represented by the function

f(x) = 9,628(0.92)x

The amount of money in account A is decreasing by 8% per year.

Part B

The table showing the amount g(r), in dollars, of money in account B after r years with number of years given as 1 2 3 4 and amount in dollars) 1,375 1,512.50 1,663.75 1,830.134.

Looking at the table,

The change per year is

(1512.5 - 1375)/1375 = 137.5/1375 = 0.1

The percentage change is 0.1× 100 = 10%

The amount in account B increases by 10%

Therefore, account B recorded a greater percentage change in amount of money over the previous year since the change in account B is 10℅ which is greater than 8% in account B
