Graphing Exponential

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.
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.

  • Compound Interest is the interest paid on both the principal and the interest you earned so far on that principal.
