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.

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
