2. The marginal cost ($) per unit when producing thousands of units of a product is recorded in the table below. units 1000 2000 3000 4000 5000 6000 7000 cost ($)/unit 1.071 1.667 2.500 3.000 2.500 1.667 1.071 (a) Graph each data point on the graph on page 4. Then draw 4 right endpoint rectangles over the interval from [2000,6000]. Shade in each rectangle. (b) Write a Riemann sum representing the total cost of producing the 20015t to 6000\" units of the product. (c) What is the cost of producing the 20015t to 6000*\" units of the product
