An electronic gadget is purchased for $500. Its depreciation rate is 30% per year. Which type of exponential function does this problem illustrate - growth or
decay? Explain how you know.

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

i think the answer is c sorry if it's wrong
