You are the efficiency manager at a silicon wafer production plant and are responsible for ensuring the productivity of the silicon molding machinery. After a review, you have found the following graph of efficiency versus time for machine #3:
Using the concepts of slopes, derivatives, and what you learned in this chapter, make a statement regarding each of the following questions:
Is machine number #3 slowly losing efficiency over time? If so, when did it suffer the biggest loss of efficiency per unit time?
What is the long term efficiency of the machine? (Hint: Long term means after a very long time of operation.)
