• 1.13.A.7 — Identify an appropriate function type to construct a function model for a given scenario. A piecewise-defined function consists of a set of functions defined over nonoverlapping domain intervals and is useful for modeling a data set or contextual scenario that demonstrates different characteristics over different intervals.
• 1.13.B.1 — Describe assumptions and restrictions related to building a function model. A model may have underlying assumptions about what is consistent in the model.
• 1.13.B.2 — A model may have underlying assumptions about how quantities change together.
• 1.13.B.3 — A model may require domain restrictions based on mathematical clues, contextual clues, or extreme values in the data set.
• 1.13.B.4 — A model may require range restrictions, such as rounding values, based on mathematical clues, contextual clues, or extreme values in the data set. UNIT 1 Required Course Content
