Exponential growth can be seen in many real-world situations. One example is population growth. When a population grows, it doesn't just add a fixed number of people each year, but the rate of growth increases over time as more and more people are added. This is an example of exponential growth.
Another example of exponential growth is the spread of a virus. At the beginning, only a few people may be infected, but as the virus spreads from person to person, the number of cases can increase rapidly.
On the other hand, exponential decay can also be observed in the real world. One example is radioactive decay. When a radioactive substance decays, the rate of decay slows down over time. However, the amount of remaining radioactive material decreases exponentially.
Another example of exponential decay is the cooling of a hot object. When a hot cup of coffee is left out, it starts to cool down. At first, it cools quickly, but as time goes on, the rate of cooling slows down, following an exponential decay pattern.
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. Use simple language and write like a student
