Answer: Yes the relationship represented by Connor's graph is a function.
Explanation:
A special relationship where each input has a single output is a function.
In the given situation, Connor will use single area each day.
Therefore, is he made a graph showing the relationship between the day of the week he worked, Monday through Saturday, and the number of square feet of much he used, then the relationship is a function.
[Since he can not work on two different lands at the same day]
So yes the relationship represented by Connor's graph is a function.
