Question

A population of bears decreases exponentially.

What is the annual factor of decrease for the bear population?

Answer 1

0.8

Explanation:

The annual factor will be found by dividing any year's population by the population of the year before. The points most easily read from the graph are the populations for years 0 and 1. Then the annual factor is ...

factor = (year 1 population)/(year 0 population) = 320/400

factor = 0.8
