20 Unit 1 - History - Gutenberg is famous for inventing printing, but he didn't really invent it. He invented a better way of printing. [2] For hundreds of years people used blocks of wood* to print. They used a knife to cut words backward in the block of wood. Then they covered the block with ink and pressed it onto paper. When they pulled the paper from the inky blocks, the words appeared on the 金属 5 paper in the right direction. In Korea and China, people printed with metal type* instead of 右向き wood. (2)Either way, printing was difficult and very slow. It took several years to make one copy of a book. [3] Books were very expensive and rare. Only ( 3a ) people could buy them, and ( 3b ) 10 people could not read. But, as ( 3c -) people learned to read, books became more popular. So people wanted to find a quicker, better and less expensive way to print books. One of these people was Johannes Gutenberg. opsugas.l Y tinU 9003 iinil 4 Gutenberg was born in Mainz, Germany, around 1400. He was good at working with metal, but probably had no idea how people printed in China. His idea was to make a piece Clarey operan 15 of metal type for each letter of the alphabet and use the letters (4)over and over. (5)He could put the type together to make words and arrange words to make pages. With ink on the type, he could press paper on them to print a page. A "printing press" machine could make hundreds of copies of a single page quickly. After that page, he could rearrange the same letters to make other words and print other pages. LISSH Si nou 5 It took Gutenberg a long time to make the type for each letter of the alphabet. When he finished the type, he didn't have enough money to make the printing press. He borrowed money from a man named Johann Fust. After many years, Gutenberg's printing press was Legione ready. Gutenberg printed his first book, the Bible, around 1455. 6 There are only twenty-one complete copies of the original Bible. They are some of the 25 most expensive books in the world. In 1987, part of a Gutenberg Bible sold for $5.3 million. 7 Today people remember Johannes Gutenberg. The city of Mainz has a statue of him and a museum. His original printing press is in the museum. (6)They print several pages a day to show that it is in good condition. earoviaU 012mu 394 words/#IN block of wood: type: vrigsypola 01 sind 7 an Oupside down & 下線部 (6) を日本 7. 本文の内容に合わ Many people & Gutenberg g Gutenberg Olt was a long Though Gu cost a lot of Hannes Rotest

(II)についてです。この問題を解く際、なぜ3kより−kの方が大きいと言えるのですか?解説等を見てもわからなかったので、教えて欲しいです。

2 [1] kは定数とする。 関数 f(x)=4(x+k)(x-34k) について, y=f(x)のグラブをコンピュータのグラフ 表示ソフトウェアを用いて表示させる。 このソフト に入力する ウェアでは, α, kの値を画面上の と、その値に応じたグラフが図1のように表示される。 の下にはα,kの値を動かすこ とができるスライダーと呼ばれるものが図2のよ うに表示されている。 スライダーのボタン●を左 に動かすと値が減少し, 右に動かすと値が増加す るようになっており, 値の変化に応じて関数のグ ラフが画面上で変化する仕組みになっている。 最 初にa, kをある値に定めたところ、図1のように, 原点を頂点とする下に凸の放物線が表示された。 (1) 図1の状態からαkのうちいずれか一方の● のみを動かしたところ, 図3のように2点 (-1,0), (30) を通る下に凸の放物線が表示さ れた。このときのの動かし方について適する ものを、次の1~4のうちから1つ選べ。 αのを右に動かす。 αのを左に動かす。 3kを右に動かす。 4 kのを左に動かす。 さらに, 図1の状態から, α, kの値を変化させると, 図4のように, グラフの軸がy軸より左にあり、 x軸の負の部分と,x軸の0<x<2の部分でそ れぞれ交わる上に凸の放物線が表示された。 こ のときのとり得る値の範囲を求めよ。 5-77A+ f(x) = a (x+k) {x-34) BEZZAH f(x) = a (x+4) (x-34) BX7ZA+ /(x) = a (x+4) (-34) 図 1 図2 図3 図4 y4 0 10 3'4 '3 + x (配点10)
