How can we determine the "human age" of a cat or dog? We used to rely on a simply formula: if the cat or dog is n years old, then its human age is 7n year. This folk formula has been updated to be more accurate and uses different formulas for dogs and cats. The following table shows a dog's age. Use it to answer questions 1-4. 01 2 3 4 5 6 7 8 Your Dog's Age Age in 01224 28 32 36 40 44 48 Human Years 9 10 11 12 13 14 15 16 17 Your Dog's Age Age in 52 56 60 64 68 72 76 80 84 Human Years 1. (2 points) Use words to explain how to compute a dog's human age. Pay particular attention to the values when a dog is between 0 and 2 years old and more than 2 years old. 2. (2 points) What is the human age of a puppy that is 6 months old? What is the human age of a dog that is 8.5 years old? 3. (5 points) Generalize your answer to question 2 to write a function where n represents how old the dog is and d(n) is the dog's human age. 4. (2 points) At what time or times in its life, n years old, will a dog be the same human age calculated under both the old and the new methods? What would be its human age?
