Task: Population of a Species C(O)
500
400
The population of a species in the wild in Asia has been
decreasing exponentially since 1980. This function represents
the wild population of the species t years after 1980:
W = 20000(0.95)'
Number Born in Captivity
3001
200
100
The Wildlife Refuge Foundation noticed this trend before 1980
and decided to try to help reduce the population decline by
breeding the species in captivity. The graph shows the number
of these animals that have been born in captivity since 1980.
