太郎さんと花子さんは,先生から出された次の問題について考えている。 問題 座標平面上に5点A(1,6), B(2.7), C(-2,-9), D(-4,-9), E (-7, 21) がある。 (i) 2次関数y=f(x) のグラフが、 3点 A, B, C を通る。 f(x) を求めよ。 (i) 2次関数y=g(x) のグラフが, 3点C, D, E を通る。 g(x) を求めよ。 先生: 2次関数のグラフの特徴をいかして, 2次関数の置き方を工夫できましたね。2次関数は, グラフが通る3点が与えられればただ一つに定まりますが、通る点から2次関数の置き方を 工夫すると、面倒な計算を避けることができますね。 では、次の問題を考えてみてください。 太郎: f(x) は2次関数だとわかっているから、f(x)=ax+bx+c とおいて計算すれば, a, b,c の値を求めることができそうだね。 3a+b=1 花子: f(x) は2次関数だから,ア という条件が必要だよ。 -730-36--15 太郎: そうだったね。 3点を通る条件が順に 49:16 ic=-a-h+g+b+c= 46-29-0-6=7, Bath=1 4-4 C-6-1774-6 a+ エンb+c=70-21-6-1+5=-930-392-15 3a+4=1 805-3 =(-4546 カン6+c=-9 a:-1 だから、この連立方程式を解くと, α = [キク h コクと求まるね。 でも, (ii)で同じことをしようとすると, 計算が面倒だね。 花子 2次関数のグラフの対称性を使うともう少しうまくできそうだね。 太郎: たしかに, 2点C, Dのy座標が等しいということから も大きいものは,頂点の座標が セ 先生: よくできました。 問題 2次関数のグラフがx軸に接し、2点 (1,1) (3,4)を通るとき、この2次関数を求めよ。 先生: この問題は、接する点の座標がわかっていないから、2次関数はただ一つに定まるかどうか わかりません。これまでの2人の学習をいかして、 2次関数の置き方を工夫して考えてみま しょう。 花子:できました。このような2次関数は2つあり、このうち、グラフの頂点のx座標が最 ス 51 ソリとなりますね。 (2) g(x)= サ ~に当てはまる数を求めよ。 とすることができるね。 花子: g(x)= サ とした方が, (i) と同じようにするよりも計算が楽にできそうだね。 (1)イ~ コに当てはまる数を求めよ。 ア の解答群 ⑩ a=1 ① a=-2 2 a=0 ③ a > 0 ④ a<0 の解答群 ⑩ d(x-3)2-9 ① d(x-3)2 +g ② d(x+3)2-9 ③ d(x+3)+q E. 21 -4 -2 0 C -9 -18- f(x)=ax2+bx+c sayaoc = 1 (qa+3+C=4 <<-19-> (配点 15) <公式・解法集 13

横線部の〈where〉は関係副詞でしょうか。解説もお願いします🙇

dangerous places. He thought, "Even if people cannot see, their feet can feel the difference of the surfaces. (3) This will warn them of danger." In 1965, after many trials and errors*,/he created some samples with his own money. 15 He gave these samples to the local government. In 1967, 230 of his blocks were placed in front of an intersection* in Okayama City, Japan. These These were the world's first Braille Blocks. 3 Over time, the use of Braille Blocks spread in Japan, and then around the A-49 world. However, accidents sometimes happened where the blocks had not 20 yet been placed. Local governments and railroad companies quickly started to place the blocks in dangerous areas. As a result, many organizations made the Tenji Blocks with their own designs. This caused some confusion. In 1996, the Japanese government started research to make standards for the Tenji Blocks. A team of scientists and 60 people with vision problems 25 worked together to find the easiest ( A ) to use. Then, in 2001, the standards were finally made. still 4 Although the designs have been standardized, there are (4)many problems. We still see various types of old blocks. They must be replaced with new standard blocks as soon as possible. In addition, the standards do 30 not say the color or material to use, or how to place the blocks.
