知识卡 · 数学M03-1-1

2 次関数のグラフ二次函数的图像

2 次関数二次函数
放物線抛物线
頂点顶点
軸对称轴

核心公式

标准形（標準形）： $y = a (x - p)^{2} + q$ ，顶点 $(p, q)$ ，对称轴 $x = p$ ； $a > 0$ 下に凸（开口向上）， $a < 0$ 上に凸（开口向下）
配方（平方完成）： $y = a x^{2} + b x + c = a (x + \frac{b}{2 a})^{2} - \frac{b ^{2} - 4 a c}{4 a}$ ，顶点 $(- \frac{b}{2 a}, - \frac{b ^{2} - 4 a c}{4 a})$
分解形： $y = a (x - α) (x - β)$ ，与 $x$ 轴交于 $α, β$ ，对称轴 $x = \frac{α + β}{2}$

卡后自测（日文题面）

2次関数 $y = a x^{2} + b x + c$ のグラフが下に凸であるとき，正しいものを，次の①～④の中から一つ選びなさい。

日文题面写「このグラフは下に凸である」，它的含义是？

①
$a > 0$ である
正解
②
頂点は $x$ 軸より下側にある
③
このグラフは， $y = a x^{2}$ のグラフを $y$ 軸の負の向きに平行移動したものである
④
$a < 0$ である

「下に凸」= 开口向上（ $a > 0$ ），「上に凸」= 开口向下（ $a < 0$ ）。字面方向与中文习惯相反，是最容易看反的术语之一，和顶点位置、平移都无关。

这张卡还有：考点与题型、解题套路、易错点、30 秒速记、更多自测题和考过这个点的真题。

真题 · 数学2021年度第1回 · Ⅰ 問1

由顶点位置与某点处两函数值相等确定二次函数并求其最小值，解两函数相等的方程求另一交点，再求两函数之差在闭区间上的最大值。

解题思路（节选）

条件 (i)「 $x = 3$ で最小」说明顶点横坐标是 3： $- \frac{a}{2} = 3$ ；条件 (ii) 是关于 $b$ 的一次方程。
最小值用「標準形」（配方）直接读出。
(2) 条件 (ii) 本身就说明 $x = 4$ 是 $f (x) = g (x)$ 的一个解，整理成二次方程后因式分解（或用「解と係数の関係」：两根之和为 2）即得另一个解。

Start from zero.
Work your way to a high EJU score.

The EJU (Examination for Japanese University Admission for International Students) is the entrance exam most international students take to enter Japanese universities. We break every syllabus topic into 3–5 minute knowledge cards, pair 267 past exams with a worked solution for every question, and put the questions you get wrong back into your review queue — from reading Japanese exam wording to finishing a full timed mock exam.

Study materials are currently written in Chinese, with the original Japanese exam wording side by side.

HOW IT HELPS

Not just a question bank — a complete way to prepare

Learn, practice, look things up, review and take mock exams, all connected, with every step recorded.

Learn by syllabus card

One topic per card: Japanese–Chinese terms, key formulas, how it's tested, solving patterns, common mistakes and a 30-second recap. Mark how well you know each one.

Past exams with solutions

Find past questions by topic, each with an approach and step-by-step solution; jump from any card to the past questions that tested it.

Spaced review and a mistake log

Anything you mark as shaky or get wrong is scheduled for review on a forgetting curve; one mistake log collects errors from self-tests, past exams and mocks.

Timed mock exams

Take a full past exam or an original mock under real time limits, get it graded automatically, then review each question and go back to its card.

Study plan and progress

Your remaining cards are spread over the days until your exam; a study calendar, accuracy trends and per-subject progress show how far you have left to go.

Japanese-language practice

Reading, listening (with audio and transcripts), writing (model answers with comments), vocabulary and grammar, in the EJU Japanese formats.

AI · POWERED BY CLAUDE

AI study features built on Claude

We're integrating Anthropic's Claude API where students most need a one-on-one tutor. These features are rolling out.

AI feedback on Japanese essaysComing soon

Scores an EJU writing answer against the rubric (relevance, structure, expression, length), points out what to improve sentence by sentence, and shows a rewritten example.

AI explanations for wrong answersComing soon

Explains exactly why the option you picked is wrong, answers your follow-up questions until it clicks, and links back to the matching knowledge card.

Oral exam practiceComing soon

Claude plays the examiner in Japanese for university oral exams, asks follow-up questions, then gives feedback and more natural phrasing for your answers.

The site's knowledge cards, past-exam solutions and practice questions were written with Claude's help and checked through multiple rounds of cross-review and automated validation.

ZERO TO EJU

How to start from zero

Not sure where to begin? Follow these four steps; each one tells you what comes next.

01
Placement
After signing up, fill in a short setup (subjects, goal, daily study time) and take a placement test to find your starting point in each subject.
02
Foundation lessons
Fill gaps from middle-school level up, and learn the matching Japanese terms in each lesson so the exam wording stops getting in the way.
03
Cards and past exams
Study a few cards a day from your plan, take each card's self-test, then try the past questions that tested that topic.
04
Mock exams
Before the exam, sit full papers under real timing; mistakes go back into your review queue and weak cards come round again.

FAQ

Frequently asked questions

Who is this site for?

International students preparing for the EJU to enter Japanese universities. The study materials are currently written in Chinese, with the original Japanese exam wording alongside; the sign-up and study pages are in Chinese for now.

I am starting from zero. Can I still use it?

Yes. After signing up you go through a short setup and a placement test, then start from foundation lessons that rebuild the basics and teach the Japanese terms used in exam questions, before moving on to the syllabus cards and past exams.

Which subjects are covered?

Mathematics (Course 1 / Course 2), Physics, Chemistry, Biology, Japan and the World, and Japanese as a Foreign Language, for both science and humanities tracks — 418 knowledge cards in total (Math 115, Physics 52, Chemistry 46, Biology 54, Japan and the World 131, Japanese 20).

Is it free?

Signing up is free. All study content opens after you log in, and your mastery, mistakes, review schedule and mock results sync between your phone and computer.

Where do the past exams come from?

They are the past EJU papers published by JASSO (Japan Student Services Organization): 267 papers from 2002 to 2026. Copyright in the original questions belongs to JASSO and they are quoted for study purposes only; every solution and explanation on the site is our own. This site is not affiliated with JASSO.
