(proficient)

The student can:

understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain exactly one element of the range. If f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to the input x. The graph of f is the graph of the equation y = f(x).
The student exhibits no major errors or omissions.

Is the relation a function (yes or no)? Explain.
a.
b.
Identify the domain and range of the relation. Is this relation a function (yes or no)? Explain.
(2, 0.5), ( 0,2.5), (4,6.5), (5,2.5)
Graph
f (x) = 2x + 2

(progressing)

There are no major errors or omissions regarding the simpler details and processes as the student:
 Recognize and recall basic vocabulary such as:
 range
 domain
 relation
 function notation
 vertical line test
However, the student exhibits major errors or omissions regarding the more complex ideas and processes.

Find the range of the relation.(4, 2), (2, 3), (1, 3).
Find the domain of the relation.
(2, 4), (8, 11), (9, 1), (4, 2)
Does the relation pass a vertical line test?
 Identify the domain and range for the given set of ordered pairs. Is this relation a function?(7,2), (1,4), (2,2), (6,5), (0,0)
