Practice54 「2」の問題です。逆の平行移動についてよく分かりません。模範解答にはx軸方向に−2、y軸方向に1だけ平行移動すると、求める放物線になる。そこまでは分かります。 ですが代入するとy−1＝−2｛x−（−2）｝^2＋3 のy−1になる理由がわかりません。誰か... Read More

There are almost no earthquakes in your country, right? No, I haven't experienced one in the U.K. Can you tell me what to do? Sure. The first priority is your safety. Hide under a desk or table to protect your head. Stay there until the earthquake stops. Then be prepared to move to a safer place. I'm sure we'll do some simulations in the evacuation drill held at school next Monday. We'll learn there what's important to do during an earthquake. Wow! That sounds great.
