示范 学习目标
- 定义一个函数作为规则，使得每个输入恰好只有一个输出，且保证函数对输入的作用是可预测的
- 给定一个函数的不同输入，预测其输出
- 将多个函数组合为一个新的函数
- 解释一个代数函数的多种表达方式，并进行比对、转换。

8.F.A.1
Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output.1
8.F.A.2
Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions). For example, given a linear function represented by a table of values and a linear function represented by an algebraic expression, determine which function has the greater rate of change.
HSF-BF.A.1
Write a function that describes a relationship between two quantities.*
HSF-BF.A.1a
Determine an explicit expression, a recursive process, or steps for calculation from a context.
HSF-BF.A.1b
Combine standard function types using arithmetic operations. For example, build a function that models the temperature of a cooling body by adding a constant function to a decaying exponential, and relate these functions to the model.
HSF-BF.A.1c
(+) Compose functions. For example, if T(y) is the temperature in the atmosphere as a function of height, and h(t) is the height of a weather balloon as a function of time, then T(h(t)) is the temperature at the location of the weather balloon as a function of time.
HSF-BF.B.4
Find inverse functions.
