题目已知二次函数的图象的顶点是(1,2)\left(1,2\right)(1,2),且经过点(0,5)\left(0,5\right)(0,5),则二次函数的解析式是（ ）A.y=−3(x+1)2+2y=-3\left(x+1\right)^{2}+2y=−3(x+1)2+2B.y=3(x+1)2+2y=3\left(x+1\right)^{2}+2y=3(x+1)2+2C.y=−3(x−1)2+2y=-3\left(x-1\right)^{2}+2y=−3(x−1)2+2D.y=3(x−1)2+2y=3\left(x-1\right)^{2}+2y=3(x−1)2+2知识点：二次函数的性质I章节：函数 / 二次函数
