How are exponential growth and decay present in the real world? Give at least 2 examples for exponential growth and 2 examples of exponential decay.

Answer 1

In the case of bacteria, exponential growth refers to their unrestrained growth as they proliferate in quantity. Another example is compound interest in finance, which is a fixed rate that grows at a particular percent each year to expand exponentially over time.

Exponential decay, on the other hand, can be compared to radioactive decay. This is when materials degrade and waste away in half over time (thus explaining its alias name, half-life material). The second example of exponential decay is a retirement fund that, as it is paid out, usually monthly, begins to diminish in terms of the amount of money left in the fund.

Answer 2

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.
