设全集U=R,集合A=｛x|(x-1)(x-3)≤0｝B={x|(x-1)(x-0)＜0｝且B含于A,求实数a的范围设全集U=R,集合A=｛x|(x-1)(x-3)≤0｝B={x|(x-1)(x-0)

设全集U=R,集合A=｛x|(x-1)(x-3)≤0｝B={x|(x-1)(x-0)＜0｝且B含于A,求实数a的范围
设全集U=R,集合A=｛x|(x-1)(x-3)≤0｝B={x|(x-1)(x-0)＜0｝且B含于A,求实数a的范围

设全集U=R,集合A=｛x|(x-1)(x-3)≤0｝B={x|(x-1)(x-0)＜0｝且B含于A,求实数a的范围
解A得
1

题错了,应该是A=｛x|(x-1)(x-3)≤0｝B={x|(x-1)(x-a)＜0｝是吧
1≤a≤3
