题目若函数f(x)满足下列两个性质:①f(x)在其定义域上是单调函数;②在f(x)的定义域内存在某个区间使f(x)在[a,b]上的值域是[1/2a,1/2b],则我们称f(x)为“内含函数”.(1)判断函数f(x)=x~1/2是否为“内含函数”?若是,求出a、b,若不是,说明理由;
If the function f (x) satisfies the following two properties: ① f (x) is a monotonous function in its domain; ② there exists some interval in the domain of f (x) (1) to determine whether the function f (x) = x ~ 1/2 is “” If it contains, find a, b, if not, explain the reason;
