在高中研究函数的性质,无非从以下几个方面着手:函数的定义域,值域(最值),单调性,奇偶性。而我们学习函数,还是利用已学的函数去探知未知的函数,都是从这几个方面着手。下面就函数的性质的研究方法,浅谈自己的一点心得和体会。首先,如果一个函数的图像已给,或我们能够做出函数的图像,那么由函数的图像我们 Studying the nature of the function in high school, nothing more than from the following aspects: the function of the domain, the range (most value), monotonicity, parity. And we learn the function, still use the function that has already learned to discover the unknown function, all proceed from these several respects. Below on the nature of the function of research methods, talk about their own little experience and experience. First, if the image of a function has been given, or we can make an image of the function, then the image of the function by us
