Answer
To determine if an exponential function represents growth or decay, check if the base
is greater than 1 for growth or between 0 and 1 for decay. The percentage rate is calculated as
for growth and
for decay.

Exponential functions can indicate either growth or decay based on the base of the exponent. If the base is greater than 1, the function represents growth; if it is between 0 and 1, it represents decay. To determine the percentage rate, you can use the formula
, where
is the base of the exponential function. For instance, if the function is
, it shows growth, and the percentage rate of increase is
. Conversely, for
, it signifies decay with a percentage rate of decrease of
.
If you need practical examples and visualizations, consider graphing these functions using software or graphing calculators—they offer fantastic insights into how the function behaves over time! You’ll see the sharp climb of growth functions and the graceful decline of decay functions, making it easier to grasp these concepts visually.
