Each day 1/2 of the money that is in a bank vault is removed. no money is added to the vault. which of the following models this situation?
a. linear function with a negative rate of change
b. linear function with a positive rate of change
c. exponential decay function
d. exponential growth function

 C. Exponential Decay function

Step-by-step explanation:

We know that In exponential decay, the total value decreases but the ratio of decreasing remains constant over time.

Here the amount in the bank account is decreasing by constant ratio of 1/2, and the amount that decreases is proportional to the money in the account, therefore, it is called exponential decay.

Hence, the given function is an exponential decay function.

total = principal × ( 1 + rate ) ^ years

total = 600 * (1.04)^5

total = 729.99

answer is c

f is the midpoint of
