Which of the following situations can be defined using an exponential function?

a)the value of the stocks decreased by $100 last year.

b)the number of bacteria increases by 700 each hours.

c)the value of the stocks increases by $10 every year you own them.

d)the number of bacteria decreases by 7% each hour.

D) The number of bacteria decreases by 7% each hour.
