1. Vertical Dilations of Quadratic Functions
Unit 4 Lesson 3

2. Lesson Objectives By the end of the lesson, students will be able to:
Graph Quadratic functions through vertical dilations.
Identify the effect on a graph by replacing
Write Quadratic Functions given a graph.

3. DO NOW

4. DO NOW – Continued

5. Graphing Calculator Group Activity
Using graphing calculators, graph the following 2 sets of functions.
Within a group of 4, each 2 students work on 1 set.
Compare and contrast the graphs, What can you conclude?

8. Terms to Know
Vertical Dilation: is s type of transformation that stretches or compresses an entire figure or graph. Vertical Stretching: is the stretching of the graph away from the x-axis. Vertical Compression: is the squeezing of the graph towards the x-axis. Reflection: is a mirror image of a graph across its line of reflection. Line of Reflection: is the line that a graph is reflected across.
