    Yesterday I stepped into a restaurant for lunch. As I was waiting my order to come, I noticed the old man in a wheelchair roll himself over to a table. No one and me seemed to notice him. I got up and go over to his table and asked if that I could get him something to drink. He smiled and said,“Thank you. You are generously. I'd like any orange juice, please.”When I was getting ready to leave, I walked by the old man's table to saying goodbye. He thanked me again and told me I had made his days, coming over and helping him out. I gave him a hug and told him he had made my day, either.

已知：如图，在Rt△ABC中，∠C=90°，AC=6，BC=8，点P在BC上运动，点P不与点B，C重合，设PC=x，若用y表示△APB的面积，求y与x的函数关系式，并求自变量x的取值范围．
