A scientist is observing the grizzly bear population in two state parks. The parks each have 150 bears when he begins observing them. The population in Park A increases by 20% each year. The population in Park B decreases by 20% each year. In each equation, y represents the bear population with respect to a number of years, x. Drag each equation to show whether it can be used to represent the bear population in Park A, Park B, or neither of these.
Question
Answer:
Nothing to drag; nowhere to drag it to.Park A's population can be modeled by
.. y = 150*1.2^x
Park B's population can be modeled by
.. y = 150*0.8^x
