The highest point on the graph of y=f(x) is (-1,6).What is the highest point on the graph of
y=4 f(x-3)+5 thanks!

函数y=f(x) 图像的最高点(-1,6),那么y=4 f(x-3)+5的最高点是多少?
考察基本的坐标变换知识,先求y最大值：4*6+5=29
再求对应x值：x=2
故所求点(2,29)
再问：谢谢回答，但我有一点不明白，f(x-3)不代表整个向右移3个单位吗，不应该先变成（2,6），然后扩大4倍变成（8,24），再向上平移变成（8,29）吗？为什么是（2,29）
谢谢了明白了一定采纳
再答：扩大4倍是对f(x)值的变化，初等数学中默认f(x)值都是y值，相当于只在纵坐标上放大了4倍，横坐标不变。
