Linear Growth, exponential growth, and repeated doublings. Linear growth occurs when a quantity grows by the same amount in each unit of time.
Exponential growth occurs when a quantity grows by the same percentage in each unit of time.
Exponential growth can be thought of as repeated doublings. When exponential growth occurs, the amount of time it takes for the growth to reach large proportions is relatively short. Identify relationships as linear or exponential. Understand and use exponential relationships to calculate various quantities.
