A. Assuming that the total cost per day, C(x), is linearly related to the total output per day, x, write an equation for the cost function. C(x)= (Do not factor.) B. The average cost per board for an output of x boards is given by C(x)-C(x)/x. Find the average cost function. C(x)= (Do not factor.) C. Sketch a graph of the average cost function, including any asymptotes, for 1sxs 30. Choose the correct graph below. OA. 500- OB. 500 D. What does the average cost per board tend to as production increases? C. OD. 500- Q 500-
