Still cоnsidering the prоblem where fоr а given compаny the cost function is given by thousаnd dollars where x is in thousands of units produced. Using the results from the previous problem it can be shown that the number of units required to minimize costs is [1]. At that value the minimum cost is [2]. Since it is the minimum, if using the second derivative test, the value of the second derivative at the point would most likely be [3]. This is a partial credit problem. Clearly label and show the work for your choices for this problem out on the paper used for submission. The work is to be included in the handwritten support work you are creating for this exam and is to be your own work. It is required to be part of the submitted file uploaded within 10 minutes after completion of the exam.
