设实数XY满足x^2+(y-1)^2=1若对满足条件xy不等式y/(x-3)+c≥0恒成立,则c的取值范围是( )
设实数XY满足x^2+(y-1)^2=1若对满足条件xy不等式y/(x-3)+c≥0恒成立,则c的取值范围是( )
设实数XY满足x^2+(y-1)^2=1若对满足条件xy不等式y/(x-3)+c≥0恒成立,则c的取值范围是( )
x=1,y=2 则2/(-2)+c>=0 则c>=1
x^2+(y-1)^2=1描述的是在该方程所表示的圆上的点。对y/x-3+c>=0分两种。①y>=0时,c>=3-x,则c>=3;②y<=0时,c<=3-x,则c<=0.综上所述,则c的取值范围是c>=3和c<=0.
