我们知道，在现行高中教材《代数》第一册中的函数部分给出了函数的性质：（Ⅰ）偶函数的图象关于ｙ轴对称。（即：对ｙ＝ｆ（ｘ）定义域中任意的Ｘ都有：ｆ（ｘ）＝ｆ（－ｘ）成立，则函数ｙ＝ｆ（ｘ）的图象关于直线ｘ＝０对称）显而易见：（Ⅱ）函数ｙ＝ｆ（ｘ）与函数...
We know that the function of the function in the current algebra in volume 1 of the current high school textbook gives the nature of the function: (I) The image of the even function is symmetric about the y-axis. (Ie, for any X in the y = f (x) domain, f (x) = f (-x) holds then the image of the function y = f (x) is symmetric about the line x = 0) : (Ⅱ) function y = f (x) and function ...
