解题方法
【推荐1】对于等式
,如果将
视为自变量
,
视为常数,
为关于
(即
)的函数,记为
,那么
,是幂函数;如果将
视为常数,
视为自变量
,
为关于
(即
)的函数,记为
,那么
,是指数函数;如果将
视为常数,
视为自变量
为关于
(即
)的函数,记为
,那么
,是对数函数.事实上,由这个等式还可以得到更多的函数模型.例如,如果
为常数
(
为自然对数的底数),将
视为自变量
,则
为
的函数,记为
.
(1)试将
表示成
的函数
;
(2)函数的性质通常指函数的定义域、值域、单调性、奇偶性等,请根据你学习到的函数知识直接写出该函数
的性质,不必证明.并尝试在所给坐标系中画出函数的图象.
