Question

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 the 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

PLEASE HELP MY WHOLE MATH GRADE COUNTS ON THIS

Answer 1

This scenario is representing an exponential decay function.

Each time you are removing half, which will be the same as divided by two.

1, 1/2 1/4, 1/8, 1/16. You can see in the denominator the powers being applied. The values are decreasing which is why it is a decay.
