Axis of Symmetry from Standard Form Vertex Form The vertex form of a parabola's equation is generally expressed as: $ y = a(x-h)^2 +k $ (h,k) is the vertex as you can see in the picture below If a is positive then the parabola opens upwards like a regular "U". If ...
A. x = -3 B. x = 3 C. y = -3 D. y = 3 相关知识点: 试题来源: 解析 B。二次函数顶点式 y = (x - 3)^2 + 1 的对称轴为直线 x = 3。选项 A 错误;选项 C 和 D 是纵坐标,不是对称轴。反馈 收藏
A. x = 3 B. x = -3 C. x = 1 D. x = -1 相关知识点: 试题来源: 解析 B。对于二次函数的顶点式 y = a(x - h)^2 + k,其对称轴为 x = h。在函数 y = -2(x + 3)^2 - 1 中,h = -3,所以对称轴为 x = -3。反馈...
