∙解：

（1）A（0，2），B（

，1）．

（2）

．

（3）如图1，可求得抛物线的顶点D（

）．

设直线BD的关系式为

，将点B、D的坐标代入，求得

，

，

∴BD的关系式为

．

设直线BD和x轴交点为E，则点E（

，0），CE=

．

∴ △DBC的面积为

．

（4）如图2，过点

作

轴于点M，过点B作

轴于点N，过点

作

轴于点P．

在Rt△AB′M与Rt△BAN中，

∵AB=AB′，∠AB′M=∠BAN=90°-∠B′AM，

∴Rt△AB′M≌Rt△BAN．

∴B′M=AN=1，AM=BN=3，∴B′（1，

）．

同理△AC′P≌△CAO，C′P=OA=2，AP=OC=1，可得点C′（2，1）；

将点B′、C′的坐标代入

，可知点B′、C′在抛物线上．

（事实上，点P与点N重合）
