Lesson 1.2.1Problems 1-54 to 1-57

Be sure to read the directions to each question carefully!!!

Problem 1-54
• Everyone in the group will start out with the same size rectangle!!
• Each shadow box will have a different height; To make shadow boxes with different heights cut different size squares from the corners for each box.
• Tables will have input values (x-values) to represent the height and outputs values (y-values) that are calculated by finding the Volume of the shadow box.
• Graph the data from your table.
Problem 1-55
• As the height changed, how did that change your length and width?
• Draw a diagram of your shadow boxes that could be used for any height. (Write your length and width in terms of height!)
• Write an equation to find the volume for a shadow box with any height.
• V = ???

Problem 1-56
• Answer all questions with complete sentences.
• A. Is the Domain limited? Are there some heights you couldn’t use?
• How can you tell using each of your multiple representations?
• B. Is the Range limited? Are there some Volumes that do not make sense?
• C. Should the graph be continuous (all points connected) or discrete (points not connected)?
• D. Compared to other graphs you have worked with, how does this one differ? What are the special features.
• E. Make as many connections between your multiple representations as you can.
Problem 1-57
• Make one graph for the group.
• Use complete sentences when explaining the relationship.
