C.) For term k(a), what are some values of a that make sense to use? What 6 points are some values of a that don't make sense to use? Explain your reasoning. * A piece of paper has an area of 81 cm. A strip is cut off that is - the original area. From that strip, another strip is cut off that is the area of the first, and so on. Here is a graph and table representing sequence k, where k(n) is the area in square centimeters of the strip of paper after n cuts. 85 80 number area in square 75 of cuts centimeters 70 65 81 60 55 1 27 50 45 2 9. 40 35 S 30 3 3. 25 20 4 1 15 10 3 4 number of cuts area in square centimeters un

4. Here is the graph of two sequences. Sequence A is labeled as triangles and Sequence B is lableed as circles. Complete the table for both sequences. 20 19 18 Term # Sequence A Sequence B 1/2 12 16 15 -1 14 13 12 11 10 3. 6 4 4. B 3 6. term number a. For Sequence A, describe a way to produce a new term from the previous term. b. For Sequence B, describe a way to produce a new term from the previous term. c. Which of these is a geometric sequence?

Be sure to clearly label each part of your response as Part A, Part B, and Part C. Use the sequence an = 7n - 5 for Part A, Part B, and Part C. Part A: If the range value is 16, what is the domain value? Show your work. Part B: If the range value is 58, what is the domain value? Show your work. Part C: Hunter says that the domain value is 6 when the range value is 37. Is Hunter correct? Explain why or why not, and show your work to support your answer.
