Profit-loss analysis. Use the revenue cost and cost function from problem 71 : R x = x 75 − 3 x Revenue function C x = 125 + 16 x C o s t function where x is in millions of chips, and R x and C x are in millions of dollars. Both functions have domain 1 ≤ x ≤ 20 . (A) Form a profit function P , and graph R , C , and P in the same rectangular coordinate system . (B) Discuss the relationship between the intersection points of the graphs of R and C and the intercepts of P . (C) Find the x intercepts of P and the break-even points to the nearest thousand chips. (D) Find the value of x (to the nearest thousand chips) that produces the maximum profit. Find the maximum profit (to the nearest thousand dollars), and compare with problem 69 B .
