Has Ian____(sell) his house yet?用所给单词的适当形式填空 f（x）=2sin（2x+π/6）如上,x∈[π/12,π/2],函数的值域是? Let us see同义句 Let us [ ] [ ] [ ] let us see的同意句 f(x)=2sin(2x+π/6)写出g(x)=f(x),x€[-7π/12,5π/12]的对称中心(必要时请加点文字说明)不对 答案是(-π/12,0) 解释说g(x)没有对称轴，所以对称中心2x+π/6=0, with +O+to do /doing/p.p造句 改错：Ian has sell his house. 如何将f(x)=2sin(x-π/6)的图像变换成g(x)=2sin(2x-π/6)的图像?
