Intro to Calculus (Class 19)
Announcements
We will not be having a test this Friday. The next test will be on Friday, October 31.
Lesson Title
Transforming Functions
Overview
The warm-up today asks students to examine the layout of a motor racing course and to create a graph comparing the speed of the race car to the distance along the track. Students then create their own race tracks,make a similar graph, and then trade the graph with another student. They then try to recreate the race track from the graph.
The lesson for the day continues from last class, focusing on transforming graphs of functions by stretching, compressing, shifting, and reflecting and then developing the algebra to represent these transformations.

Key Attitudes
Math is about thinking creatively.
Key Ideas
Graphs of functions can be transformed by shifting, flipping, compressing, or combination of these.
How the graph of a function changes can be described using both words and algebra.
Key Skills
I can predict how the graph of a function will change as the result of changes to the equation that represents the function.
