Question

Without graphing, how can you determine if a function is an exponential growth or exponential decay function?

Answer 1

Simply identify the trend of the values in the data

Explanation:

For an exponential growth function, the dependent variable will be increasing as the independent variable increases; For instance, if money in an account earns interest continuously then the amount will be increasing with time.

For an exponential decay function, the dependent variable will be decreasing as the independent variable increases; For instance, the weight of a radioactive element diminishes with time.
