### General Information

**Subject Area:**Mathematics

**Grade:**912

**Domain-Subdomain:**Functions: Interpreting Functions

**Cluster:**Level 2: Basic Application of Skills & Concepts

**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.

### Test Item Specifications

MAFS.912.F-IF.1.1

MAFS.912.F-IF.2.5

**Assessment Limits :**

For F-IF.1.2, in items that require the student to find a value given a

function, the following function types are allowed: quadratic,

polynomials whose degrees are no higher than 6, square root, cube

root, absolute value, exponential except for base e, and simple

rational.

Items may present relations in a variety of formats, including sets of

ordered pairs, mapping diagrams, graphs, and input/output models.

In items requiring the student to find the domain from graphs,

relationships may be on a closed or open interval.

In items requiring the student to find domain from graphs,

relationships may be discontinuous.

Items may not require the student to use or know interval notation.

**Calculator :**

Neutral

**Clarification :**

Students will evaluate functions that model a real-world context for

inputs in the domain.

Students will interpret the domain of a function within the real-world

context given.

Students will interpret statements that use function notation within

the real-world context given.

Students will use the definition of a function to determine if a

relationship is a function, given tables, graphs, mapping diagrams, or

sets of ordered pairs.

Students will determine the feasible domain of a function that models

a real-world context.

**Stimulus Attributes :**

For F-IF.1.1, items may be set in a real-world or mathematical

context.

For F-IF.1.2, items that require the student to evaluate may be

written in a mathematical or real-world context. Items that require

the student to interpret must be set in a real-world context.

For F-IF.2.5, items must be set in a real-world context.

Items must use function notation

**Response Attributes :**

For F-IF.2.5, items may require the student to apply the basic

modeling cycle.

Items may require the student to choose an appropriate level of

accuracy.

Items may require the student to choose and interpret the scale in a

graph.

Items may require the student to choose and interpret units.

Items may require the student to write domains using inequalities.
