A1.7 Unit Overview

Students are introduced to quadratic relationships and compare them to linear and exponential relationships. They analyze graphs, tables, and equations in three forms to identify and interpret key features of quadratic functions. Students will model situations with quadratic functions and make predictions and decisions based on these models.

Learning goals: Sub-Unit 1: Introduction to Quadratic Functions (Lessons 1–7 + Quiz) • Justify whether a function is linear, quadratic, exponential, or none of these. • Identify and interpret key features of quadratic functions in graphs and tables. • Compare and contrast properties of quadratic functions. Sub-Unit 2: Standard Form and Factored Form (Lessons 8–13 + Practice Day + Quiz) • Determine key features and graph quadratic functions from standard- and factored-form equations. • Write quadratic equations from a graph, description, or criteria. • Identify and interpret key features of quadratic functions from equations. Sub-Unit 3: Vertex Form (Lessons 14–18 + Practice Day) • Create quadratic models to solve problems in context. • Describe the effect of transformations on key features of a parabola and its equation in vertex form.
