对于求两个函数图象交点坐标的问题,很多同学对此感到无从下手.其实函数即是二元方程,求两个函数图象的交点坐标就是求两个二元方程的公共解,这可以通过解方程组来解决.下面以2001年的中考题目为例说明.
For the problem of finding the coordinates of the intersection of two functions of an image, many students cannot start with this. In fact, the function is a binary equation. Finding the coordinates of the intersection of two functions is to find the common solution of two binary equations. Solve the equations to solve. The following example of the 2001 exam questions.
