Final answer:
The data for Amit's puppy shows a function because each week has a unique weight value for the puppy.
Step-by-step explanation:
The data for Amit's puppy does show a function. A function is a relationship where each input (independent variable) has exactly one output (dependent variable). In this case, the independent variable is the number of weeks and the dependent variable is the weight of the puppy. If each week has a unique weight value for Amit's puppy, then it satisfies the criteria for being a function.
