原题(2008年台湾)如图1,坐标平面上有一透明片,透明片上有一拋物线及一点P,且拋物线为二次函数y=x2的图形,P的坐标(2,4).若将此透明片向右、向上移动后,得拋物线的顶点坐标为(7,2),则此时P的坐标___.思考1变平移方向.原题中“透明片向右、向上移动后,得拋物线的顶点坐标为(7,2)”能否通过改变平移的方向平移拋物线,得抛物线的顶点坐标为(7,2)?把常规的平
The original title (Taiwan in 2008) is shown in Figure 1. There is a transparent film on the coordinate plane. The transparent film has a parabola and a point P, and the parabola is a graph of the quadratic function y = x2. The coordinates of P (2,4) This transparent film to the right, up to move, get the vertex coordinates of the parabola (7,2), then the coordinates of P ___. Thinking 1 change the direction of translation. In the original title “transparent film to the right, up After moving, get the vertex coordinate of the parabola as (7,2) ”Can we translate the parabola by changing the direction of translation to get the vertex coordinate of the parabola as (7,2)
