数Ⅰの二次関数の問題です。 「d>0であるから、dの2乗が最小となるときdも最小となる。」という断りが重要な理由を教えていただきたいです…!よろしくお願いします!!

18 00000 最大・最小の文章題 (2) 基本例題 67 座標平面上で, 点Pは原点Oを出発して, x軸上を毎秒1の速さで点 (6,0) まで進み, 点Qは点Pと同時に点(0, -6) を出発して、 毎秒1の速さで原点 0まで進む。 この間にP, Q間の距離が最小となるのは出発してから何秒後 ② 基本 66 か。 また、その最小の距離を求めよ。 CHART & SOLUTION √f(x) の最大 最小 平方したf(x) の最大・最小を考える t秒後のP, Q間の距離をdとすると, 三平方の定理から d=√f(t) の形になる。ここで d>0 であるから, d² = f(t) が最小のときも最小となる。 解答 出発してから t秒後の P Q 間の距 離をdとする。 P Q は 6 秒後にそ れぞれ点 (6,0),(0, 0) に達するか ら << 0≤t≤6 このとき, OP=t, OQ=6-tであ るから, 三平方の定理により d²=12+(6-t)^ "/id=2t²-12t+36 YA MOTUJOLAH P 6 基本形に変 GAA ,J3 x=30 €32 $HAON とりうる値の範囲。 ①点Qのy座標は t-6 UNDOJ =2(t-3)2+18 ① において, d2 は t=3 で最小値 18 をとる。 d0 であるから, d が最小となるときdも最小となる。 よって、3秒後にP, Q間の距離は最小になり, 最小の距離は √18=3√2 2656512=286 基本形に変形。 ←軸 t=3 は ① の範囲内。 この断りは重要!ある
