E BD fu)=>sing111-9+3=)+2 = 2 sind.9°+2=-25in 21.9723. 3. 已知函數f(x)=2sin(3x+6)+4,函數y=sinx經過下列哪些選項的操作後可得函數y=f(x)的圖形。 (A) 將 y = sinx的圖形先水平伸縮為ㄧㄢ 倍,鉛直伸縮為2倍,再向左平移6單位,向上平移2單位 y=2sin3(x+6242. (B)將 y=sinx的圖形先水平伸縮為一倍,鉛直伸縮為2倍,再向左平移2單位,向上平移4單位 4=25in3(x+2)+4=25in (3x+6)+4 , (C) 將 y=sinx的圖形先水平伸縮為3倍,鉛直伸縮為ㄐㄧ 倍 再向左平移6單位,向上平移2單位 ·4 = \/\sin 3(x+6)+2 2 (D)將y = sinx 的圖形先向左平移6單位,向上平移2單位,再水平伸縮為 倍,鉛直伸縮為2倍 4=2543(x+6)+2 (E)將y=sinx的圖形先向左平移6單位,鉛直伸縮為2倍,再向上平移4單位,水平伸縮為 倍
