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?
(1 point)
Oy = 0.95 0.05
O y = 100x0.95
O y = 100x0.05
y = 100(0.05)
y = 100(0.95)
The exponential function that represents the rate of decay of the compound is:
y = 100 * (0.95)^x
where x is the number of years.
