动态题是近几年来中考数学的热点问题,除作压轴大题外,在客观题中也占有一席之地.而在客观题中,以动点生成函数图象问题较为常见,这类问题通过点、线或图形的运动构成一种函数关系,生成一种函数图象,将几何图形与函数图象有机地融合在一起,体现了数形结合的思想,充分考查学生观察、分析、归纳、猜想的能力以及综合运用所学知识解决问
In recent years, the dynamic question is a hot issue in the mathematics test for senior high school entrance examination, in addition to making a big problem in the finale, but also occupies a place in the objective question.And in the objective question, the problem of generating the function image with the moving point is more common, Line or graphic movement constitute a functional relationship to generate a function image, the geometric image and the function of the image organically integrated together, reflecting the combination of the idea of digital form, fully examine the students observe, analyze, summarize, guess Ability and comprehensive use of knowledge learned to solve the problem
