# Access Point #: MAFS.912.F-IF.1.AP.3a

Recognize that the domain of a sequence is a subset of the integers. .
Clarifications:

#### Essential Understandings

Concrete:

• Use a T-chart and manipulatives to pair the values in the domain to the values in the range.
• Identify what is and is not a function when given a set of values in a relation.
Representation:
• Use a T-chart to predict the output (y-value).
• Understand the following related vocabulary: domain, range and sequence.
General Information
Number: MAFS.912.F-IF.1.AP.3a
Category: Access Points
Date Adopted or Revised: 07/14
Cluster: Understand the concept of a function and use function notation. (Algebra 1 - Major Cluster) (Algebra 2 - Supporting Cluster)

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
