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

Map elements of the domain sets to the corresponding range sets of functions and determine the rules in the relationship.
Clarifications:

#### Essential Understandings

Concrete:

• Evaluate an expression using substitution (ex: find the value of x + 1 = y, for example when x = -1, y = 0 using manipulatives). Representation:
• Recognize in an ordered pair that the first number represents the domain (x-value) and the second number represents the range (y-value).
• Understand function notation (e.g., in y = f(x) is another way to write y is f(x), also stated f of x).
• Understand x as the input and y as the output (cause and effect).
• Understand that the graph of f is the graph of the equation y = f(x).
General Information
Number: MAFS.912.F-IF.1.AP.1b
Category: Access Points
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.
