I am asked to give an example of exponential growth and decay in my math class.

Would it be ok for me to say that an allowance is an example of exponential growth?

not likely - mine never was. It was constant.

Why not just use google? It will provide many examples.

Actually, an allowance is not an example of exponential growth but rather an example of linear growth. Exponential growth and decay refer to situations where the quantity being measured or studied grows or decreases at an increasing or decreasing rate, respectively. In a mathematical context, exponential growth typically follows the pattern of repeated multiplication by the same number.

A common example of exponential growth is the growth of a population over time. For instance, if a population doubles in size every year, the growth can be described as exponential. Each year, the population is multiplied by the same factor (in this case, 2) and the growth rate becomes increasingly rapid as the population gets larger.

On the other hand, exponential decay refers to a quantity decreasing at an accelerating rate. Radioactive decay is a classic example of exponential decay, where the amount of a radioactive substance decreases at a consistent percentage rate over time.

It's important to differentiate between linear, exponential, and other forms of growth or decay. In the case of an allowance, if the amount stays the same over time, it would be considered constant or linear growth, rather than exponential.
