The Size of a Bird Population on an Island Can

question 114

Short Answer

The size of a bird population on an island can be described by a sinusoidal graph. The number of birds on the island decreased from a maximum of 20,000 in 1943 to a minimum of 12,000 in 1989, and then began increasing again. Find a function that describes this behavior and use it to estimate the number of birds on the island in 2012. Round to the nearest whole number.
