Try Korea SAT

The craziest math question forever in Korea SAT.

30. Function g(x) which is defined at x>a, and fourth function g(x) which the coefficient of the highest degree is -1 satisfy followings.

(A) Every real number x bigger than a satisfies (x-a)f(x)=g(x).
(B) If α, β is different number, function f(x) has same local maximum, M, when x=α and x=β.
(C) The number of x which makes f(x) has local maximum or minimum is bigger than the number of x which makes g(x) has local maximum or minimum.

If β-α=6√3, what is the Find the minimum value of M?

응 나형 좁밥

I'm OP.

If β-α=6√3, what is the Find the minimum value of M? → If β-α=6√3, what is the minimum value of M?

what does “function” and fancy letters mean i am fat stupid american who eats cheeseburger and gets shot

That is easier than I thought.
It's just a tool to define.

이거 2017 수능 가형인디?

진짜루?
수준 떨어졌네 저거 극값이나 함수값 문제 아님?
미적1 수준의 문제가 왜 가형에??

by "fourth function" you mean a fourth degree polynomial? ax^4+b^3+...+e?

right

Please describe the constants as C.

나도 모름. 그래프 그리면 미적1으로 다 풀림. 물론 f(x)=g(x)/(x-a)으로 놓고 미분해서 풀겠다 하면 미적2 써야 되긴 하지만...
그런데 이 문제 정답률 EBS 기준 1.6%고 실제 정답률 0.1% 이하로 추정되고 있음. 전국에서 168명 맞힌 나름 어려운 문제.

216???임 답
풀어보니 생각보다 복잡하네
어려운거보다 지저분한 문제임
함정을 많이 깔아두

딩동댕

ㅋㅋㅋㅋㅋㅋㅋㅋㅋ
근데 이거 생각보다 개어려움 진까 최대값 구하면서 이게 맏나 헛갈림

실제로 f(x)가 삼차함수 아니냐는 질문 올라왔음. 이게 이 문제 최대 함정이라는 평가.

난 나누기도 까먹었다.

작년이 불수능이였다는 이유가 있었군.
아 땅수능이였나?

사실 나누기는 가장 어려운 문제임
1/3 정확한 값 구할수도 없음
유사값을 도출하는거지

Not even gonna attempt this, fuck Korean """people"""

작년 수능(2018수능) 30번은 진짜 그래프만 그리면 풀이과정 5줄 쓰고도 끝낼 수 있는 진짜 쉬운 문제였는데 정답률 생각보다 낮게 나와서 EBS 강사들 당황했었다는 이야기가...

the answer is 216

lmao don't talk to me nerd I don't want to be infected with your virginity

ㅋㅋㅋ EBS 알바뛰던 시절 그립다.
꽁짜로 수특 수완 받았는뎅
그거 출제자 의도 반영안되면 불려감

That is an easy problem than you thought.

난 수능 출제자 될 일은 없지만 만약 되면 선택지 비율 44445 깨고 33456 만들어서 다 조질 거임

So the nerd can do arithmetic but he can't read eh? Well here it is in your insect language 꺼져 버려.
Understand now Kim???

you learn those in high school you probably forgot and don't have a STEM degree

:(

ㅠㅠ
I'm hurt.
And I brought a solution for you.

It's easier than U thought.

Sorry. Not with my mouse.
But if you draw a graph, you can see where it makes the problem difficult.
You can't trust the graph.

역시 수능답지여서 정확하게 써있네
난 많이 생략했는데

What do U think of this problem

maybe you should make the math slightly easier so you have time to learn english cuz yours is atrocious

5?
I hope it's correct.

cute frog

My calculus is rusty, last I studied was 2 years ago

이 문제 나형 치고 진짜 어렵던데

I was three years ago.

가형이라는데 OP가

아휴... 왜 나형이라 했는지 다시 생각해보셔요

Gods I was so strong back then. Don't make me post Tübitak shit I was solving

ㄴㄴ 나도 위에서 처음에 저렇게 말했는데
직접 풀어보니 좀 난해함
물론 개념적으로는 미1 내용인데
문과선에서 풀 수있는 문제가아님
좀 많이 꼬왔더라

다시 생각해보세요()

아 그문제 미안해 ㅋㅋㅋㅋㅋㅋㅋㅋ

괜찮아 ㅋㅋㅋㅋㅋㅋ

내가 아직 한국어를 마스터하지 못했어

this is a reason why koreans are shit at English, or school that get this kind of test/question.
hard words and strong words everywhere, something that is not commonly used in conversations, contracts and presentation.
lmao, only essay writing is acceptable for this shit
