Masters of the Desert “Bedouin” is a name given to some of the people who live in North Africa and the Middle East. Unlike most people, many Bedouins do not ( 24 Instead, they are nomads, which means that they are always moving about. They walk around the hot deserts of countries like Egypt and Israel, leading their camels and sheep to gras and water. Life in the desert is not easy, but over thousands of years, Bedouins have developed unique skills to help them survive. Some people estimate that there are around 20 million Bedouins in the world today. However, ( 25 ). Because many of them are traveling, it is impossible to count them all. In recent years, however, many Bedouins have given up their traditional way of life. This is because the amount of land controlled by governments has increased, which has made it harder for the Bedouins to travel freely. Some of them now live in urban areas and have regular jobs, such as driving taxis and working in restaurants. Some Bedouins have found work with the Israeli army as trackers. A tracker is a person who follows people by using signs left on the ground, such as the marks left by feet or tires. Trackers must know their environment well and be quick to notice anything unusual. ( 26 ), with their desert survival skills, Bedouins are excellent trackers. About 1,600 of them are now serving in the Israeli army, and their ability to notice dangers along Israel's borders is helping to protect the countily. 1 sleep lying down 2 live in one place 3 eat meat or fish 4 use paper money 1 their exact numbers are unknown 2 there were many more in the past 3 the groups have no government 4 they all meet once every year 1 Naturally 2 Occasionally 3 Secondly 4 Equally

(2)なのですが丸がついているところからx=0がわかるのですよね? 計算の仕方とそもそもどうしてその式から値が出るのかが分かりません。

指数関数を含む関数の最大値·最小値の求め方をマスターしよう! STEP 2 解法MASTER テーマ8 指数関数を含む関数の最大·最 目標 [例題8} 関数y=4"+ 4* ー-2(2"+)+4 がある。 2* 1 -=tとおくとき,yをtの関数で表せ。 2* (2) yの最小値を求めよ。また,そのときのxの値を求めよ。 考え方 yをtの2次関数に帰着させる。tのとり得る値の範囲に注意する。 解法のプロセス 1 =tとおき,xの関数からtの関数に置き換える。 2* 0 2*+ tのとり得る値の範囲を相加平均と相乗平均の大小関係を利用して求める。 3tの2次関数に帰着させて,最小値を求める。 解答 2 =1の両辺を2乗すると (2"+)- +2+-P 1 2x+ 2* 4*+2+ 4* よって 4*+-=-2 4* したがって、与式は y=(t?-2)-2t+4 すなわち y=-2t+2 …答 (2) g(t)=D?-2t+2 とおくと g(土)3 (t-1) +1 1 2*> 0, ->0であるから, 相加平均と相乗平均の大小関係により 2* 2* =2 2* 1 等号が成り立つのは, 2*=- 2* すなわちx=0 のときである。 ソ=g() 1 よって t=D2*+ -2 最小 2* 2 以上より,t22において, y=g(t)の グラフは,右の図のようになり, g(t)は t=2のとき, 最小値2をとる。 1 0 1 2 ここで、t=D2 となるのは, 2*=- 2* よって, x=0のとき, 最小値2…答 すなわちx=0のときである。
