Answer 1

Well, exponential growth can be the unrestricted growth of bacteria as they multiply in numbers. Another example is in financing when we're talking about compound interest, which is a fixed rate which grows at a certain percent to grow exponentially over time.

On the other hand, exponential decay can be like when we talk about radioactive decay. This is when materials, again over time, decompose and waste away in half (thus explaining its alias name, half-life material). The second example for exponential decay is a retirement fund which as it's being paid out, usually monthly, it starts decreasing in terms of how much money is left in the funds.
