    所以y=Vx2+4+1>2,故B错误:对于C,命题3x∈R,12”,故C正确:对于D,A={x|x2+x-6=0}={-3,2},又因为BA,当B=0时,m=0,当B0时,由1-3或1-2,m=)或m=-1,故实数m的mm。11集合为02引故D不正确:故选:AC11.己知b>0,若对任意的x∈(0,+oo),不等式ax3+3x2-abx-3b≤0恒成立.则()A.a<0B.a2b=3C.a2+4b的最小值为12D.a2+ab+3a+b的最小值为6-6W3【答案】ACD【详解】因为ax3+3x2-abx-3b=x2(ax+3)-b(ax+3)=(x2-b)(ax+3),ax+3x2-abx-3b≤0恒成立,即(x2-b)(ax+3)≤0恒成立,因为b>0,所以当x∈(0,VB时,x2-b<0,则需ax+3≥0,当x∈(V万,+∞)时,x2-b>0,则需ax+3≤0,故当x=√b时,ax+3=0,即a√b+3=0,所以a<0且a√b=-3→a2b=9,故选项A正确,选项B错误;9所以a2+4b=2+4b≥.4b=12,0Vb93当且仅当9=4b时,即b=3时取等,故选项C正确;b因为a2+b+3a+b=a2+9+3a+9=a-2+=a小-3}-2
