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
ParkA, Park B, or neither of these.
