讲函数的对称性主要是讲奇偶函数图像的对称性,函数与反函数图像的对称性.前者是函数自身的性质,而后者是函数的变换问题.下文中我们均简称为函数的对称性.函数的对称性在近几年高考中屡见不鲜,对于解决其它问题也很有帮助,同时也是数学美的很好体现.现通过函数自身的对称性和 The symmetry of the function is mainly about the symmetry of the odd-even function image and the symmetry of the function and inverse function image. The former is the property of the function itself, and the latter is the problem of the function transformation. In the following, we will simply call it the symmetry of the function. The symmetry of functions has become commonplace in the college entrance examination in recent years. It is also helpful for solving other problems, and it is also a good embodiment of the beauty of mathematics. Now through the symmetry of the function itself and
