The population of Bengal tigers in a region of India can be modeled by the function P = 450(0.85), where P is the population and I is the number of years since 2000.
What is the Bengal tiger population in 2000?
and by what percent does the tiger population decrease each year?

(a) The population in 2000 is 450

(b) 15% decreases each year

Step-by-step explanation:

Given

--- since 2000

Solving (a): The population in 2000

First calculate t

--- years since 200

So, we have:

Solving (b): Rate of population decrease

A function that decreases is represented as:
