在高中数学解题过程中,函数图象的运用比较普遍,也是常用的解题方法之一。函数图象可以通过简单的坐标轴展现出来,在题目中所有的信息均可在图象中标注,让我们能更直观明了地理解题意。所以,我们要掌握好作函数图象的基本方法,学会利用函数图象分析解决问题。一、函数图象在选择题中的运用选择题在数学试题中大约占了1/3的比例,一般难度不大,难度较大的一般为后两题,而且经常会出现需要运用函数图象进行解答
In high school mathematics problem solving process, the use of function images is more common, and it is also one of the commonly used method to solve problems. Function images can be displayed through simple axes. All the information in the title can be marked in the image, so that we can understand the problem intuitively and intuitively. Therefore, we must master the basic method of function image, learn to use function image analysis to solve the problem. First, the use of function images in multiple-choice questions The multiple-choice questions in mathematics questions account for about 1/3 of the proportion of generally difficult, more difficult for the latter two questions, and often need to use the function diagram Like to answer
