A bird sanctuary used to receive 10,000 birds per year. The number of birds migrating to the sanctuary is decreasing at the rate of 5% each year. Identify the exponential decay function that models the situation. Then find the bird population after 4 years.

a - y = 10000 (0.5); 7800

b - y = 10000 (0.95) t; 8000

c - y = 10000 (0.9) t; 7900

d - y = 10000 (0.95) t; 8145
