Click on the blanks to reveal the answers.

- 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
- Find the perimeter of Figure 10. Interactive button. Assistance may be required. _____________________ 32
- Which figure has a perimeter of 47? Interactive button. Assistance may be required. _____________________ Figure 15
- 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, ...}
- 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}
