19、有????121222fxfxxxf?????????（Ⅰ）求實數(shù)a的取值范圍；（Ⅱ）對于給定的實數(shù)a，有一個最小的負數(shù)??Ma，使得??0xMa?????時，??44fx???都成立，則當a為何值時，??Ma最小，并求出??Ma的最小值解：（Ⅰ）∵????121222fxfxxxf?????????22212121122222xxxxaxbxcaxbxcabc?????????????????????????21204axx????，

20、∵12xx?，∴0a?∴實數(shù)a的取值范圍為??0??（Ⅱ）∵??2224422fxaxxaxaa?????????????，顯然??02f??，對稱軸20xa???。（1）當424a????，即02a??時，??20Maa????????，且??4fMa??????令2424axx????，解得242axa????，此時??Ma取較大的根，即??2422422aMaaa????????，∵02a??，∴??21422Maa??????（
