1. On a piece of notebook paper sketch the following figures, or create the figures with toothpicks, to see the puzzle formed with this activity.




2. Copy the table on your paper.

Figure number	Perimeter



3. Create Figure 4 and Figure 5 using the same pattern. Hint: Use the table to determine the pattern of the sequence.

Click on the blanks to reveal the answers.

1. Write a function to find the perimeter of each figure. Assume that each side is 1 unit long. Interactive button. Assistance may be required. _____________________ y = 3x + 2


2. Find the perimeter of Figure 10. Interactive button. Assistance may be required. _____________________ 32


3. Which figure has a perimeter of 47? Interactive button. Assistance may be required. _____________________ Figure 15


4. What is the domain of the function? Is the domain discrete or continuous? Write the reasonable domain in set notation format. Interactive button. Assistance may be required. _____________________ Domain is the Figure number, which would be a discrete set. {1, 2, 3, 4, 5, ...}


5. What is the range of the function? Is the range discrete or continuous? Write the reasonable range in set notation format. Interactive button. Assistance may be required. _____________________ Range is the perimeter values, which would also be discrete. {5, 8, 11, 14, 17, ..., 3x+2}
