A wildlife refuge has 200 birds when it is first established. It is so successful that the number of birds increases by 25% every year.
Write a function to model the situation.
Find the number of birds present after 7 years.

(b) 954 birds after 7 years

Step-by-step explanation:

Given

--- initial

--- rate

Solving (a): The function.

This is represented as:

So, we have:

Express percentage as decimal

Solving (b): Birds after 7 years

This implies that we calculate f(7)

--- approximated

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0
