Answer:
Decay
Step-by-step explanation:
Here, we want to know the kind of exponential function that the problem illustrate
From the question, we are told of a depreciation by 30%’per year
what this mean is that it loses its value at a rate of 30% per year
Hence, we can conclude that the change in value in the next year is 30% less than what we had the year before it
So in this instance, we can conclude that what we have is a decay since we are talking about a loss in value
