写真の赤丸⭕️の部分が、いつもプラスにするのかマイナスにするのかあやふやになります、、、 どうやって見分けるのか分かりやすく教えてください🙏🙇‍♀️

84 第2章 2 次 Think 例題 33 練習 ** 33 平行移動(②2) (1) 放物線y=-x+4x+1 は放物線y=-x2-6x+7 をどのように 平行移動したものか. (2) ある放物線Cを,x軸方向に2,y 軸方向に1だけ平行移動すると、 飲物線 y=2x-3x+4 になった。 放物線Cの方程式を求めすると 考え方 (1) 頂点の移動を考える. どちらをどちらに平行移動するのかを、しっかりおさえ (2) 放物線y=2x-3x+4 を逆に, x軸方向に -2,y 軸方向に1だけ平行移動 WALL ると, 放物線Cが得られる. Focus 解答 (1)y=x2+4x+1=-(x-2)2+5 より,頂点は点 (25) y=−x²−6x+7= −(x+3)²+1651 より,頂点は点(-3, 16) 頂点(-3.16) が点(2.5)に移動するから x 軸方向に, 2-(-3)=5 5-16=-11 (2) 放物線y=2x2-3x+4... ① を逆に, x軸方向に ―2 y軸方向に -1) だけ平行移動したものが, 放物線Cである. y軸方向に だけ平行移動している. よって,x軸方向に5,y 軸方向に-11y=2x²3x+4 よって, y=2x2+5x+5 逆の移動を考える 605061 放物線C つめる。 よって、①のxをx+2, y を y+1 におき換えて, _y+1=2(x+2)2-3(x+2)+4 STOS CASERT y=2(x²+4x+4)=3x-6+3 (8) 「x軸方向にか 軸方向に g [x軸方向に 頂点の座標をます JEAN- (移動した分) (後(前) ちなよ! 軸方向に-g VJ 頂点の移動で考えて もよい. C 放物線 C' (1) 放物線y=2x²-4x-1 をどのように平行移動すると, 放物線 y=2x2+8x- になるか. (2) ある放物線Cを,x軸方向に2,y 軸方向に3だけ平行移動すると, 線y=-x²+2x+3 になった. 放物線Cの方程式を求めよ. 放物 p.92 Cor <グ 対 たすあて とす であ ので 点 京 とな

【IV】 次の(A), (B)の設問に答えよ。 ((A)11点,(B) 6点) (A) 次の英文を読んで、 下の設問に最も適切な解答をせよ。 選択式の設問は記号 (アイウエ・・・) を1つ選んで答えること。 A World Bank report recently released suggests climate change could, force 216 million people across six regions to migrate within their countries in the next 30 years, with ""hotspots" emerging within the next nine years ( 2 ) urgent steps are taken. The "Groundswell Part 2" report examines how climate change is a powerful driver of migration within a nation because of its impact on people's livelihoods through droughts, rising sea levels, crop failures and other climate-related conditions. The original Groundswell climate report was published in 2018 and detailed projections and analysis for three world regions: sub- Saharan Africa, South Asia and Latin America. "Groundswell 2" conducted similar studies on East Asia and the Pacific, North Africa, and eastern Europe and Central Asia. Both studies established different scenarios to explore potential future outcomes and identify internal climate in- and out- migration hotspots in each region that is, the areas from which people are expected to move, and the areas to which they might go. The study suggests that by 2050, sub-Saharan Africa could see as many as 86 million internal climate migrants; East Asia and the Pacific, 49 million; South Asia, 40 million; North Africa, 19 million; Latin America, 17 million; and eastern Europe and Central Asia, 5 million. To slow the factors driving climate migration and avoid these worst-case outcomes, the report recommends a series of steps world leaders can take, including reducing global emissions ( 4 ) the goals established by the Paris 2015 climate agreement, and taking steps to better understand the drivers of internal climate migration, so appropriate policies to address them can be developed.
