二次函数的图象和性质应用广泛,历来是各地中考命题的热点.近年来,对二次函数的考查形式越来越多样化,并且在试题的命制方面作出了很多尝试,其中有一类问题是将抛物线与几何变换有机结合.类型一抛物线的平移例1(2016·绥化)将抛物线y=3(x-4)~2+2向右平移1个单位长度,再向下平移3个
The quadratic function has a wide range of applications and properties, and has always been a hot topic in the test area throughout the country. In recent years, the test forms of quadratic functions are becoming more and more diversified, and many attempts have been made on the test questions. The problem is to combine the parabola with the geometric transformation. Type 1 Parabola Translation Example 1 (2016 · Suihua) Pan the parabola y = 3 (x-4) ~ 2 + 2 to the right by 1 unit length and then translate it downwards by 3
