核心理论
练习前按清晰顺序掌握本章核心概念。
Input-output relationship
A function maps each allowed input to one output. Formula, table, and graph are different representations of the same relationship.
Parameters and graph
Parameters change slope, position, amplitude, or rate of change. Read the key features before plotting individual points.
Domain and interpretation
The domain states which inputs are allowed. In a real model, also check whether the output is physically meaningful.
Calculator/CAS use where allowed
Use a suitable representation, state the rule, and keep every numerical or algebraic step equivalent. Finish with estimation, an inverse operation, or substitution as a check.
Interpreting parameters
Use a suitable representation, state the rule, and keep every numerical or algebraic step equivalent. Finish with estimation, an inverse operation, or substitution as a check.
Real-world functions
Use a suitable representation, state the rule, and keep every numerical or algebraic step equivalent. Finish with estimation, an inverse operation, or substitution as a check.
Documentation of solutions
Use a suitable representation, state the rule, and keep every numerical or algebraic step equivalent. Finish with estimation, an inverse operation, or substitution as a check.

例题讲解
逐步查看方法，并理解每一步为何成立。
Worked function example
For f(x) = 4x - 5, find f(4) and the x-intercept.
- 1Substitute x = 4: f(4) = 4·4 - 5.
- 2For the intercept set f(x) = 0: 4x - 5 = 0.
- 3Solve for x and check the point on the graph.
f(4) = 11, x-intercept = 5/4
Reasoning example
Before calculating, explain the key idea from “Calculator/CAS use where allowed” and which conditions must be checked.
- 1Define the idea in one clear sentence.
- 2Connect it to a representation, law, or formula.
- 3State a restriction, unit, or final check that makes the solution valid.
The answer should show not only which rule is used for “Calculator/CAS use where allowed”, but also why it is valid here.
