Question

After 5 years. c.) What is happening to the rate of change of sales as time goes on? d.) Does the rate of change of sales ever equal zero? a. The rate of change after 1 year is thousand items per year. (Round to three decimal places as needed.) b. The rate of change after 5 years is thousand items per year. (Round to three decimal places as needed.) c. What is happening to the rate of change of sales as time goes on? A. It always decreases. B. It always increases. C. First it increases, then it decreases. D. First it decreases, then it increases. d. Does the rate of change of sales ever equal zero? No Yes
