在学习函数问题时往往需要数形结合利用函数图像,有时会涉及图像的对称性.问题1函数y=f(a+x)与y=f(a-x)的图像关于x=a对称吗?分析我们先从具体函数f(x)=x3谈起,
When learning the function problem, it is often necessary to combine the function image with the number-shape, sometimes involving the symmetry of the image. Question 1 Is the image of y = f (a + x) and y = f Let’s start with the concrete function f (x) = x3,
