Question

In a certain geographic location, a herd of elephants is declining at a rate of four percent every year. If there are currently 62 elephants in the herd, create an exponential decay function to model the problem. Let y represent the number of elephants after t years.(1 point)

y=62(0.6)t


y=62(1.04)t


y=62(0.04)t


y=62(0.96)t

Answer 1

y = 62(0.96)^t

Explanation: a 4% yearly decline multiplies the population by 1 - 0.04 = 0.96 each year, so y = 62(0.96)^t.
