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.
