This lesson prepares students for a few things they will be asked to do in the associated Algebra 1 lesson: evaluating quadratic functions in vertex form for various inputs, extracting the coordinates of the vertex of a graph from vertex form of the associated quadratic function, and reasoning about whether the vertex corresponds to a maximum or a minimum value of the function.
Lesson overview
- 16.1 Warm-up: Math Talk: When \(x\) Is -7 (5 minutes)
- 16.2 Activity: Four Functions (20 minutes)
- 16.3 Activity:Four More Functions (20 minutes)
Learning goals:
- Evaluate quadratic functions given in vertex form and notice patterns in the outputs.
- Identify the vertex of the graph of a quadratic function.
- Use given tables of values to sketch graphs of quadratic functions.
Learning goals (student facing):
- Let’s use vertex form to reason about a graph.
Standards:
- This lesson builds towards the standard:CCSS.HSF-IF.C.7.aMS.F-IF.7aMO.A1.IF.C.7
