Answer:
1. superscript number
2. exponential growth
3. exponential decay
Explanation:
In an exponential expression, the exponent (superscript) number indicates how many times the factor (i.e., the base number) is repeated. For example, the expression 2ⁿ indicates that the base number (2) is repeated n times.
The exponential growth indicates how a specific quantity increases over time, thereby the curve drawing an exponential function. The exponential growth is produced when the rate of increase of a quantity in a given time is directly proportional to the quantity itself.
The exponential decay describes how a specific quantity proportionally decreases across time, thereby showing a percentage decrease rate over time.
