又是詳解錯了嗎？AE的斜率更小吧？確認一下

2. 作圖如下 y +B(3,5) C(5,3) A(1,1) x 0 E(2,-3) F(8,-6) ID(0, -7) L 由上圖可知滿足題意之斜率最小值為 -6-3 MCF = =-3 8-5

請問為什麼E是空集合？詳解寫的但我不知道為什麼 我想說x可以是1、2、3不就三個都是？

1. ) 下列哪些集合與集合S={1,2,3}相等? (A){xx為不大於3的正整數(B){3,2,1} 芒果合 (C){1,2,2,3,3,3} (D) {x | (x-1)(x-2)(x-3)=0} (E) (x| (x-1)²+(x-2)² + (x-3)² =0}

請問這題算法🙏
