二次関数の最小値についての質問 画像はある問題の解説です。 「関数のグラフの軸x=-a」 という部分について、 シンプルにx=aでは駄目なのでしょうか。 回答していただけると嬉しいです。

■5y=2x²+4ax = 2(x+a)²-2a² (1) 関数のグラフの軸 x = -α と定義域 0≦x≦2の位置関係 を考えて,次の3つの場合に分ける。 0≦x≦2におけるこの 関数のグラフは, 下の図の放物線の実線部分である。 (i) -α <0 のとき (ii) 0≦a≦2 (2<a のとき のとき Px=2 x=0 x=-a x=0 x=-a x=2 x = 0 x=2 x=-a のように変 をイメージすればよい。 定義域に軸を 含むか... (ii) 含まないか... (i), (ii) で考える。 放物線を固定して, 定義 域を移動させるとイメー ジしやすい。
