TEST ITEM SPECIFICATIONS
 Reporting Category: Algebra

Item Type(s):
This benchmark will be assessed using:
MC
,
FR
item(s)
Also Assesses:
MA.912.A.2.13 Solve realworld problems involving relations and functions.
 Clarification :
Students will determine the domain and range of relations.  Content Limits :
In items requiring students to determine the domain and/or range from an equation, only linear and quadratic functions may be used.
Domains and ranges may be listed as inequalities (e.g., 0 < x ≤ 60 for domain), or written as a sentence.
Items should utilize function notation, as appropriate.
Items may present relations in a variety of formats, including sets of ordered pairs, tables, graphs, and input/output models.
In items requiring students to determine the domain and/or range from a graph, only linear, quadratic, or continuous piecewise functions may be used.
 Stimulus Attributes :
Items may be set in either realworld or mathematical contexts  Response Attributes :
Multiplechoice and fillin response items may require that students provide the least value (lower bound) or greatest value (upper bound) in the domain or range, or an endpoint of the domain or range.
Fillin response items may have a negative answer.

 Test Item #: Sample Item 1
 Question:
An economics teacher plotted the value of a stock on 11 different days during a 500day period and used line segments to connect them. In the graph below, the horizontal axis is measured in days and the vertical axis is measured in dollars.
Based on the graph, which of the following best describes the range of the value of the stock for this 500day period?
 Difficulty: N/A
 Type: MC: Multiple Choice
