指数函数与其他函数复合后形成复合函数,如y=a~(f(x))和y=f(a~x)(a>0且a≠1).通过对这些复合函数性质的研究,搞清指数函数与其他代数函数之间的联系,明确复合函数的性质与指数函数的性质的区别与联系.下面对指数函数型复合函数的图像与性质的应用举例说明.1.复合函数的图像把指数函数y=a~x(a>0且a≠1)的图像 The exponential function is combined with other functions to form complex functions such as y = a ~ f (x) and y = f (a ~ x) (a> 0 and a ≠ 1). By studying the properties of these complex functions, Find out the relationship between the exponential function and other algebraic functions and make clear the difference between the nature of the complex function and the nature of the exponential function.Examples of the application of the image and property of the exponential function compound function are illustrated below.1.
