Chapter 6.5, Problem 41E

(a)

To determine

To graph: The function $\overline{C}\left(x\right)=\frac{1000+30x+0.1x^2}{x}$ on the window $\left[-10,10\right]$ by $\left[-200,300\right]$.

(b)

To determine

To graph: The function $\overline{C}\left(x\right)=\frac{1000+30x+0.1x^2}{x}$ on the window $\left[0,50\right]$ by $\left[0,300\right]$.

(c)

To determine

To find: The graph which is better to represent the average cost per set from part (a) or part (b)

(d)

To determine

To find: The minimum average cost and the number of units that gives the minimum average cost on the window $\left[0,250\right]$ by $\left[0,300\right]$.
