The graph shows the balance of an account earning quarterly compound interest.
which statements are true about the function?
select each correct answer.
a. the practical domain is x≥100 , so the account balance is always greater than $100.
b. the practical range is y≥100 , so the account balance is always positive.
c. the graph is ascending, indicating that the account balance is increasing over time.
d. the account balance will be $222.11 after 40 years.
e. the point (1,102.02) represents an initial account balance of $102.02.

Just as Kiara11003 said, the answers are

"The practical range is y≥100 , so the account balance is always positive."

"The graph is ascending, indicating that the account balance is increasing over time."

"The account balance will be $222.11 after 40 years."

I have just taken the test and these answers were correct.

Step-by-step explanation:

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
