The exact shape of the curve is subject to discussion, but the point of diminishing marginal utility is that, as you get more and more money, the increment in utility for each extra dollar diminishes.

这条曲线的确切形状还有待讨论,但是边际效用递减规律的重点在于,你得到的钱越多,每额外的一美元的增长效用会相对减小

The idea is that for any amount of money-- if this x is the amount of money that I receive-- utility as the function of the amount of money I receive is downwardly-concave.

这种观点是对于任何数量的货币,假设我得到x数量的货币,随着货币的增加,边际效用呈,向下凹进去的曲线

Let me finish the picture here; here's my demand curve, here's my constant marginal cost at c, and I want to use this picture on the left now to figure out what the monopoly quantity is.

先把图画完,这条是需求曲线,这个是边际成本常量c,下面我们通过左边的图像,来找出垄断产量
