Explain graphically how indifference analysis can be used to derive a demand curve.Instructions:The diagram on the left shows three optimums (points a, b, and c) corresponding to three prices for good X (P₁= $8, P₂= $4, and P₃= $2). Corresponding quantities are shown on the horizontal axis. Use the tool provided 'Demand' to plot the three price-quantity combinations corresponding to points a, b, and c.
