Going Over Homework:

How can graphs of functions be used to determine a person’s weight on a different planet?The purpose of the 2001 Mars Odyssey Mission is to study conditions on Mars.The findings will help NASA prepare for a

possible mission with human explorers. The graph compares a person’s weight on Earth with his or her weight on Mars. This graph represents a direct variation, which you studied in the previous lesson.

IDENTIFY GRAPHS

In this course, you have studied several types of graphs representing special functions.

What follows is a summary of these graphs.
