The water depth in a pond is initially 48 inches and decreases at a rate of 0.5 inches per day
through evaporation. Write a function that represents the depth of the pond at a given time.
What will be the depth of the pond after 8 days?

What are the domain and range of the function below? a) domain: (-4,0) range: [-2,infinity) b) domain: (-3,0) range: [-2,infinity) c) domain: (-infinity,infinity) range: [-2, infinity) d) domain: [-2,infinity) range: (-infinity,infinity)
