**Answer: a) 16.9491525424 %**

**b) 124322 ( approx )**

**Step-by-step explanation:**

**a)** The population in 2009 = 118000

While the population in 2013 = 138,000

Thus, the total percentage change in the population from 2009 to 2013,

**b) **Let the function that shows the population after x years since 2007,

Where a and b are any unknown number,

Since, for x = 0, f(0) = 118000 ( given)

⇒

⇒

Now, For x = 6, f(6) = 138,000 ( given )

⇒

⇒

⇒

Hence, the function that shows the population after x years since 2007,

For, x = 2,

⇒ **The predicted population in 2009 is approximately 124322. **
