일계조건 + 극대 이계조건을 만족하는 해는?
일계조건 + 극소 이계조건을 만족하는 해
일계조건 + 극대 이계조건을 만족하는 해
이계조건을 만족하지 않는다고 해서, 꼭 극대/극소해가 아닌 것은 아니다
일계조건은 만족하고 이계조건을 만족하지 않는 경우
Answer explanation
The correct answer is the option that satisfies both the given conditions, which is '일계조건 + 극대 이계조건을 만족하는 해'.

이계미분량을 이용한 이계조건 증명
일계조건 + (이계조건의 부정)
함수의 볼록과 오목
Answer explanation

이윤극대화의 일계조건은 무엇인가?
Π′(𝑄∗)=𝑀𝑅(𝑄∗)−𝑀𝐶(𝑄∗)=𝑎−2𝑏𝑄∗−𝑐=0
Π′′(𝑄∗)=−2𝑏<0
총 세액 T(Q) = tQ
이윤함수 = TR(Q) - TC(Q) - T(Q)
Answer explanation
The correct choice for profit maximization is Π′(𝑄∗)=𝑀𝑅(𝑄∗)−𝑀𝐶(𝑄∗)=𝑎−2𝑏𝑄∗−𝑐=0

정부가 독점기업이 판매하는 물건 1단위당 t원의 세금을 부과할 때, 세금을 반영한 이윤함수는?
Π′(𝑄∗)=𝑀𝑅(𝑄∗)−𝑀𝐶(𝑄∗)=𝑎−2𝑏𝑄∗−𝑐=0
이윤극대화의 일계조건
TR(Q) - TC(Q) - T(Q)
총 세액 T(Q) = tQ
Answer explanation
The correct choice is TR(Q) - TC(Q) - T(Q), which represents Total Revenue minus Total Cost minus Total Tax.

일반 독점모형에서 이윤함수는?
P(Q)Q - C(Q)
𝑃′(𝑄∗)𝑄∗+𝑃(𝑄∗)−𝐶′(𝑄∗)=0
이윤함수 = TR(Q) - TC(Q) - T(Q)
C(Q) = cQ
Answer explanation
In a general monopoly model, the profit function is represented as P(Q)Q - C(Q), where P(Q) is the price function and C(Q) is the cost function.

일반 독점모형에서 일계조건은?
𝑃′′(𝑄∗)𝑄∗+2𝑃′(𝑄∗)<0
𝑃′(𝑄∗)𝑄∗+𝑃(𝑄∗)−𝐶′(𝑄∗)=0
일계조건 + 극소 이계조건을 만족하는 해
일계조건은 𝑃′(𝑄∗)𝑄∗+𝑃(𝑄∗)=𝑐
Answer explanation
The correct answer is 𝑃′(𝑄∗)𝑄∗+𝑃(𝑄∗)−𝐶′(𝑄∗)=0, which satisfies the first-order condition in a general monopoly model.
