Which of the following scenarios demonstrates an exponential decay?

A. Value of a dollar affected by constant deflation
B. Value of a dollar invested in a savings account
C. Value of a dollar affected by constant inflation
D. None of the above

Answer 1

First: what does "decay" mean? If you know the meaning of "decay," you should be able to eliminate the least likely answers immediately.

Answer 2

idk what it means @mathmale

Answer 3

I always strongly recommend looking up and writing down words you encounter in Math questions that you don't know.

"Decay" could be loosely translated into "diminishing in volume," "diminishing in value," "fading away," and so on. Do you know the word "diminishing?"

Now look at the four answer choices. Which choices seem to involve "growth?" which seem to involve "decay?"
