Step-by-step explanation:
Exponential decay describes a situation in which the dependent variable is reduced by the same factor when the independent variable is increased by the same amount.
A — the population is increasing, not being reduced
B — the amount is cut in half when time increases by 15 years (exp. decay)
C — the number of teams is cut in half when the number of rounds increases by 1 (exp. decay)
D — the amount is cut in half when time increases by 3 hours (exp. decay)
E — the population is increasing, not being reduced
