Lesson 2: Graphs of Equations in Two Variables
Duration of Days: 5
Lesson Objective
Know:
Equations and graphs of absolute value, parabolas, and circles
Do:
Use standard form, intercepts, symmetry and reflection to graph absolute value, parabolas and circles in the coordinate plane
How can we sketch absolute value, quadratic, and circle graphs?
How can we write the equations of these graphs?
A.CED.2 - Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales.
Graph, read, and analyze graphs of absolute value, quadratic, and circle functions.
Page 139, #94: A satellite is in orbit around the moon. A coordinate plane containing the orbit is set up with the center of the moon at the origin, as shown in the graph below, with distances measured in megameters. From the graph, determine the closest and the farthest that the satellite gets to the center of the moon.
For advanced students, provide more challenging functions and applications.
For struggling students, provide extra examples and visuals.
