Problem

The diagram shows the graphs of y=x3y=x^3 and y=f(x)y=f(x). The graph of y=x3y=x^3 is transformed to the graph of y=f(x)y=f(x) by a sequence of transformations.

(a) Describe fully a suitable sequence of transformations. Make clear the order in which the transformations are applied.

[5]

(b) You are given that f(x)=a(x+b)3+cf(x)=a(x+b)^3+c.

State the values of the constants aa, bb and cc.

题目中文翻译

图中显示的是 y=x3y=x^3y=f(x)y=f(x) 的图像。y=x3y=x^3 的图像通过一系列变换得到 y=f(x)y=f(x) 的图像。

(a) 完整描述一种合适的变换顺序。需要清楚说明这些变换应用的先后顺序。

(b) 已知 f(x)=a(x+b)3+cf(x)=a(x+b)^3+c

写出常数 aabbcc 的值。
