Knowledge
Students know:
- Distinguishing characteristics of functions.
- Conventions of function notation.
- In graphing functions the ordered pairs are (x,f(x)) and the graph is y = f(x).
Skills
Students are able to:
- Evaluate functions for inputs in their domains.
- Interpret statements that use function notation in terms of context.
- Accurately graph functions when given function notation.
- Accurately determine domain and range values from function notation.
Understanding
Students understand that:
- A function is a mapping of the domain to the rangeFunction notation is useful in contextual situations to see the relationship between two variables when the unique output for each input relation is satisfied.
