Yesterday you explored 401(k)s. Was that an example of exponential growth or exponential decay?
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
DECAY | arrow_right_alt | b>1 |
GROWTH | arrow_right_alt | b<1 |
Is it growth or decay?
What is the percent of increase/decrease?
Is it growth or decay?
What is the percent of increase/decrease?
If the percent of increase is 12%, what is the base?
If the percent of decrease is 12%, what is the base?
Formally, the equations for exponental growth and decay can be written as:
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
DECAY | arrow_right_alt | |
GROWTH | arrow_right_alt |
