Types of Functions

Scientists are studying the population of a rare species of primates, known as Javan gibbons, on the Raja Ampat Islands in Indonesia. They are studying the gibbons on three different islands: Batanta, Misool, and Salawati. The scientists studied the population growth and recorded the data in the table.

Answer :

The first difference is linear with time and pop. growth. The second difference is constant

How to solve

The data presented shows the growth of the Javanese gibbon population on three different islands over time.

Analyze data to determine growth function by plotting and observing curve shape. Since the table only has data, analyze trends by comparing consecutive terms.

To do this, we can calculate the first difference and the second difference in the population data.

The first difference:

- Swing: 40 - 30 = 10, 50 - 40 = 10, 60 - 50 = 10

Example: 60 - 50 = 10, 75 - 60 = 15, 90 - 75 = 15

- Salavati: 80 - 60 = 20, 100 - 80 = 20, 120 - 100 = 20

The second difference:

- Batanta: 10 - 10 = 0, 10 - 10 = 0

- Example: 15 - 10 = 5, 15 - 15 = 0

- Salavati: 20 - 20 = 0, 20 - 20 = 0

The first difference is linear with time and pop. growth. The second difference is constant. The population growth model is a linear function:

M(x) = mx + b

where x is the time in years, m is the slope (population growth rate), and b is the y-intercept (initial population).
