A manufacturer estimates that, if each order for raw materials contains x units, the total cost of acquiring and storing the annual supply of materials x will be

C(x)=2x+x80000dolares

Determine the number of units required for the cost to purchase and store equal to or less than $ 20,000

Graph the function, indicating domain, path, asymptotes, and cuts with the axes, then mark on the graph the part pertinent to the given situation and estimate the optimal size of the order
