Guided notes teaching students how to find domain, range, and values in each when given a set of coordinates, a function map, a table, and a graph. Values are written using function notation, as in find f(3) or find x when f(x) = 0, and students must also determine if the set, map, table, or graph are functions by checking for a repeating domain value or using the vertical line test. The performance question at the end has students express a set of values using multiple representations, such as
