【简答题】对于在[a,b]上有意义的两个函数f(x)与g(x),如果对任意的x∈[a,b],均有|f(x)-g(x)|≤1,则称f(x)与g(x)在[a,b]上是接近的,否则称f(x)与g(x)在[a,b]上是非接近的.现在有两个函数f(x)=log t (x-3t)与g(x)=log t ( 1 x-t )(t>0且t≠1),现给定区间[t+2,t+3]. (1)若t= 1 2 ,判断f(x)与g(x)是...
【简答题】如果函数f(x)=-x 2 +2ax在区间[1,2]上是减函数,那么实数a的取值范围是a≤1a≤1.如果函数f(x)=-x 2 +2ax与函数 g(x)= a x+1 在区间[1,2]上都是减函数,那么实数a的取值范围是0<a≤10<a≤1.
【单选题】如果在区间[1,2]上函数f(x)=x 2 +px+q与g(x)=x+ 1 x 2 在同一点取相同的最小值,那么f(x)在该区间上的最大值是(  )
