Question 3: What is the utility function? Edit the explanation of this paragraph's utility function in the reference book 1, a function that represents the quantitative relationship between the utility obtained by consumers in consumption and the combination of goods they consume. It is used to measure consumers' satisfaction from consuming a specific combination of goods. Using indifference curve can only analyze the combination of two commodities, while using utility function can analyze the combination of more commodities. The expression is: u = u (x, y, z, ...), where x, y and z respectively represent the quantity of various commodities owned or consumed by consumers, and the u on the left side of the formula is ... The academic literature in this paragraph explains the utility function as 1, and the definition of the utility function is: let f be the preference relationship defined in consumption *** X, if x, xf. The key of weighted P norm method is to determine the weight coefficient. There are two basic methods, one is the old learning method, and the weight coefficient 3 is selected according to the relative importance of the objective function. A person's utility should be a function of wealth X, which can approach everyone's utility function through a series of psychological tests. Different decision makers should have different utility functions. First of all, we seek the properties satisfied by utility functions or some special types of utility functions. This is a theoretical hypothesis. The model they built with the mathematical function is called "utility function". According to this model, it can be assumed that people can decide to generate a certain level of benefits in every possible time allocation and pursue the maximization of benefits. 5. The cost of type I vehicle, sometimes called utility function, is u = ao+alx- moxibustion xC. Travel time of d-I-mode transportation. Transportation cost of c-I-mode transportation. 6. In order to evaluate the control, we need a set of functions as evaluation indicators: j (t) = ∑∞ k = 0k γ u (t+k) = u (t)+j γ (t+1) (2) where U(t)=U[R(t), A(t). Functions of a class need not all be public. Some functions are privately defined and serve other functions. Such a function is called a utility function.
Question 4: What's the use of lily? Lily's medicinal lily bulbs are fleshy and rich in starch and protein. Cooked food has a unique charm, is a treasure in vegetables, and is a multifunctional healthy food. Nutritional and medicinal costs The nutritional status of lily is mostly starch, protein and fat, and there are other alkaloids. Lily's medicinal bulbs have always been fleshy, rich in starch and protein. Cooked food has a unique charm, is a treasure in vegetables, and is a multifunctional healthy food. Nutritional and medicinal costs The nutritional status of lily is mostly starch, protein and fat, and there are other alkaloids. It has always been considered as a nourishing product. Pharmacological research shows that lily has excellent antitussive effect, and can increase blood perfusion in the lungs and improve the effect of moistening the lungs. Lily also has a certain calming effect. Lily is used as medicine in Chinese medicine, and nervousness is also used for people with chronic lung diseases, such as bronchitis, chronic bronchitis or emphysema, who cough or expectorate for a long time.

Treat pulmonary tuberculosis with chronic cough, phlegm and blood. After the fever has gone down, the residual heat is clear and the voice of God is weak. Berberi edema. According to Bielu, except edema, abdominal distension, spleen fullness, cold and heat, sadness all over, breast, cough and nasal discharge. Can be used for treating lung heat, dyspnea, cough, hemoptysis, low fever, dysphoria, panic and insomnia.
Question 5: What is marginal utility and total utility? What is the difference between them? Total utility refers to the sum of satisfaction obtained by consuming a certain amount of a certain commodity, which is expressed by TU.
Marginal utility refers to the degree of satisfaction of an item per unit consumption, which is expressed by MU.
The total utility is equal to the sum of all marginal utilities until this number; The marginal utility of consuming a certain amount is the change of the total utility of the last unit.
In addition, if the marginal utility is greater than 0, the total utility increases; If the marginal utility is less than 0, the total utility decreases; The marginal utility is equal to 0, and the total utility is the largest.

Question 7: What is the function of honey water? Honey health care Baduanjin restores fatigue, especially after staying up late. Of all natural foods, honey requires the highest energy for brain neurons. Fructose and glucose in honey can be quickly absorbed and utilized by human body, improving the nutritional status of blood. Usage: A cup of honey water at noon can eliminate the honey accumulated after a big meal, promote the normal secretion of gastric acid, enhance intestinal peristalsis, and obviously shorten the defecation time. Usage: Taking 25 grams of honey on an empty stomach every morning and evening has the functions of diminishing inflammation and resolving phlegm, moistening lung and relieving cough, and loquat honey has the best cough relieving effect. Usage: One Sydney, sliced with honey, several times a day. The ingredient of hangover honey contains a kind of fructose that most fruits don't have, which can promote the decomposition and absorption of alcohol, help to sober up quickly and relieve headache after drinking. Usage: Before drinking, eat 50g honey or a few pieces of biscuit bread coated with honey, and drink honey water after drinking. After getting up in the morning, drink honey on an empty stomach. Advantages: preventing constipation, nourishing skin and prolonging life. Disadvantages: Drinking honey water on an empty stomach can easily increase the acidity in the body, which will lead to gastric ulcer or duodenal ulcer for a long time. It is recommended to drink honey water after meals 1.5-2 hours. Note: it is best to use 30 degrees for people with bad stomach. It means: get up early every day and drink light salt water on an empty stomach, and drink honey water every night before going to bed. The reason for this is that drinking light salt water in the morning can dilute the blood that feels very sticky, and has a little anti-inflammatory, stomach-moistening and laxative effects; Drinking honey water at night is helpful for beauty and supplementing various trace elements. Therefore, it is more scientific to leave honey water to drink at night and get up in the morning to drink light salt water. Of course, some people have difficulty defecating, so drinking honey water early will help defecate, or it depends on their physical condition. My personal recommendation is to drink a cup of hot milk with a spoonful of honey before going to bed every night. Because milk contains more potassium, honey is rich in magnesium. Studies have shown that potassium plays an important role in the conduction of nerve impulses and the coagulation of blood. It can relieve mood, inhibit pain, prevent infection and reduce menstrual blood loss. Magnesium has a sedative effect on the central nervous system of the brain, which can regulate psychology, eliminate tension and reduce stress. So it is very helpful for women. In addition, milk and honey are rich in B vitamins, which can relieve sleep.
Question 8: What is the average utility? Average utility is an important content of utility theory in microeconomics. If a consumer can buy goods and bring him satisfaction, then suppose that this satisfaction can be measured by utility. If there is no such commodity, once the consumer buys this commodity, it will bring great utility, and with the increase of the number of similar commodities he buys, although the utility is still increasing, the satisfaction brought by the unit commodity is decreasing. The average utility is to divide the total satisfaction (that is, the total utility) obtained by purchasing a commodity by the number of commodities, and get the average satisfaction level brought by each commodity to consumers.
