40、t引导定语从句，并在从句中作主语。,关系代词引导的定语从句,已知函数f(x)=x2-4x+a+3,g(x)=mx+5-2m,当a=0时，对任意的x11,4,总存在x21,4,使f(x1)=g(x2）成立，求m的范围。,当a=0时，f(x)=x2-4x+3,g(x)=mx+5-2m即 x2-4x+3=mx+5-2m 在1,4上有实数解 的问题整理得 h(x)=x2-(4+m)x+2m-2=0 在1,4上有实数 所以 1中情况为 当对称轴(4+m)/2小于等于1时 即 m小于等于-2时 h(1)*h(4)小于等于0 解得 m大于等于5或m小于等于-1 这种情况下m取小于等于-2 2种情况为 当对称

41、轴(4+m)/2大于等于4时 即 m大于等于4时 h(1)*h(4)小于等于0 解得 m大于5或m小于等于-1 这种情况下m取大于等于5 3种情况为 当对称轴(4+m)/2大于等于1小于等于4时 即m大于等于-2小于等于4时（4+m）2-4(2m-2)=m2+24恒大于0 所以 m大于等于-2小于等于4 能满足条件 综上所述 m的取值范围是m小于等于4或m大于等于5,关系代词引导的定语从句,f(4)=a+3 f(2)=a-1若t=2，7-2t=3=f（4）-f（2）若t2,假设也存在，则t2-4t+a+3-(a+3)=2t-7t=3+2 3-2均不符合条件t2时若2t=0,7-2t3,D=3因

42、此不存在当t0时t2-4t+a+3-(a-1)=7-2tt=-1一共有两个-1和2,关系代词引导的定语从句,一氧化碳二氧化碳混合气体15克，标况下体积10.08升，则一氧化碳质量？所含二氧化碳在标况下的体积？,标准状况下(STP)气体摩尔体积为 224L/mol。,设二氧化碳物质的量是X,一氧化碳是Y44X+28Y=1522.4(X+Y)=10.08解得X=0.15Y=0.3所以 二氧化碳0.15mol，一氧化碳0.3mol.,关系代词引导的定语从句,已知二次函数f(x)=4x2-2(p-2)x-p-5.若在区间（-1，1）内至少存在一个实数c，使f(c)大于0.求实数p的取值范围。,判别式0,对称轴x=(p-2)/2 结合图像观察,若使f(c)0恒成立 1)当对称轴小于0时,只要保证f(1)0 即(p-2)/20，4-2（p-2)-p-50=p1 2)当对称轴等于0时，也是要f(1)=f(-1)0 即(p-2)/2=0，4-2（p-2)-p-50=p无解 3）当对称轴大于0时，只要保证f(-1)0 即(p-2)/20，4+2(p-2)-p-50=p5 所以 p的解集为(-，1）（5，+）,关系代词引导的定语从句,THE END,
