Sullivan is filling a swimming pool and graphs the amount of water in the pool as a function over time.

Is the function is discrete or continuous? Explain.

1.) It is continuous because both time and the amount of water are increasing continuously.

2.) It is continuous because time is increasing continuously and the amount of water is not.

3.)It is discrete because both time and the amount of water are increasing continuously.

4.) It is discrete because time is increasing continuously and the amount of water is not.
