解题思路: (1)△OPA的底边是OA=4,OA边上的高等于P点的纵坐标,面积就可以得到; (2)根据(1)中得到的函数可以判断函数的类型,进而判断自变量的取值范围; (3)把y=-0.5x+3代入(1)中的解析式,就可以得到s与x的关系式; (4)△QOA是以OA为底的等腰三角形,则Q在OA的垂直平分线上,因而Q的横坐标是2,代入一次函数解析式就可以得到点的坐标.
解题过程:
解:(1)S=(1/2)×4y=2y;
(2)S是y的正比例函数,0<y<3;
(3)S=-x+6,0<x<6;
(4)∵Q在线段OA的垂直平分线上,因而横坐标是2,
把x=2代入y=-0.5x+3,得到y=2,因而Q的坐标是(2,2).
最终答案:略
