01Input-output relationship
A function maps each allowed input to one output. Formula, table, and graph are different representations of the same relationship.
02Parameters and graph
Parameters change slope, position, amplitude, or rate of change. Read the key features before plotting individual points.
03Domain and interpretation
The domain states which inputs are allowed. In a real model, also check whether the output is physically meaningful.
04Calculator/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.
05Interpreting 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.
06Real-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.
07Documentation 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.
