is the relationship for olivia’s puppy’s weight in terms of time increasing or decreasing? explain your response.

Increasing. For every week that goes by, Olivia's puppy is gaining one pound. 6-5= 1  14-13= 1. Gaining a pound every week makes the puppies weight increase. Since increase is the term for something is bigger than number or value than before, Olivia's puppies' weight is increasing. 

I hope this helps!
