"A demand curve shows different quantities that would be bought during a period if the price were at different levels,assuming that all other factors influencing purchases remained constant.It is of very limited if any use.since at any one time there is only one price.not many,and also since as prices do change over time,most of the other factors influencing demand change,too."Discuss.
