A chemical compound decays at a rate of 5% per year. If the initial size of the compound is 100 grams, what is the exponential function that represents the rate of decay?

Answer 1

The exponential function that represents the rate of decay can be represented by the formula:

y = 100 * (0.95)^x

Where:
y = size of compound after x years
x = number of years

So, the exponential function that represents the rate of decay is:

y = 100 * (0.95)^x
