# Lesson 17

Parameters and Graphs

These materials, when encountered before Algebra 1, Unit 6, Lesson 17 support success in that lesson.

### Lesson Narrative

In preparation for the associated Algebra 1 lesson, this lesson is focused on generating and practicing informal language used to describe transformations of a graph. Students have opportunities to describe changes to a graph in a way that makes sense for them, and opportunities to make their language . more precise (MP6). This will enable students to have this language at the ready. They also spend more time drawing connections between transformed graphs and their equations.

### Learning Goals

Teacher Facing

- Analyze how a change in each parameter of the function changes the graph.
- Graph quadratic functions given in vertex form.

### Student Facing

- Let’s talk about moving graphs around the plane.
