5 October 2009 Big Idea : Observation and description of changes in the world around us are the first steps in finding and learning about patterns. INV 5 Essential Question: How can a graphing calculator help me to discover relationships between variables? Mathematic Reflection 5 Pg.68 Dear Friend, I have learned how to use a graphing calculator in the last couple of days. I learned how to graph equations. I also learned what equations will go through the x-axis and which will not (equations containing x will go through the x-axis). I also learned that I don’t have to clear my equations to prevent it from being visible (I press enter over the equal sign.) Best Wishes, Anuvrat
 * 1 **** . Write a letter to a friend explaining how to use a graphic calculator to make graphs and tables. Use a specific example to illustrate your explanation. **

** b **** . **** Does your equation give you enough information to make a table or graph? Why or why not? **
===** I believe **** my equation has enough information to make a table. I can make a table by changing n to a number and then calculating how many tents or tent space it takes for that amount of customers. I can make a graph by plotting the coordinate pairs I got from the table. Finally I add a title and label my axes. **===

Joey and Peter are making tables to show who the fastest bicycler is.
=== 1. Who is the fastest bicycler? === === 2. What happens to Joey after the 5th mile? === ===** 3. ** Peter slows down after the 3rd mile why ===

** Summary **
===** In this investigation I learned how to use a graphing calculator (some parts of it at least). I learned how to graph equations and also turning equations into tables. Another skill I learned how to graph equations without graphic calculators (not perfected yet). **===
