| Example: |  |
when a > 0 and the b is greater than 1, the graph will be increasing (growing).
For this example, each time x is increased by 1, y increases by a factor of 2.
Such a situation is called Exponential Growth.
Decay:
|
| Example: |  |
when a > 0 and the b is between 0 and 1, the graph will be decreasing (decaying).
For this example, each time x is increased by 1, y decreases to one half of its previous value.
Such a situation is called Exponential Decay.
