Algebra 2

Lesson Title
4.1.3 How can I graph it quickly?

Overview
In today’s class students reflect on the work they did in the last class and come up with a way to find change (some) equations which are in the form y = ax^2+bx+c into graphing form. As time permits they will begin to put what they have learned in the last few classes to work by creating models of situations.

Vocabulary
interest
simple interest
compound interest

Key Attitudes
Willingness to work as a group to help meet individual and group goals.

Enduring Understandings
Changes in various parameters have specific effects on graphs of parent functions in the coordinate plane.

Essential Question
What changes can we make to a parabola’s graph?
What changes can we make to the equation y=x^2?
How do changes in the equation relate to changes in the graph?

Key Knowledge
An equation for a parabola can be written in the form y = a(x-h)^2+k
Each parameter for a parabola in the form y = a(x-h)^2+k controls a certain aspect of the graph of the parabola.

Key Skills
I can explain how each parameter in equations of the form y = a(x-h)^2+k effects the graph of the function.
