    Eliana lives in Anchorage, Alaska. For her senior project, she is doing a report on some of the aspects of living in Alaska that are different from other states in the United States. She knows that Alaska has very late sunsets in the summer, so she has recorded the time the sun set every week for 10 weeks, starting on June 1. Her table and graph of the data are shown at right. Homework Help ✎

    1. The summer solstice marks the longest day of the year. Based on Eliana’s information, when do you estimate summer solstice was?

    2. If Eliana continues to record and graph sunset times through December, what will her graph look like? Sketch a prediction.

    3. What kind of function would you use to model this data? Explain your choice.

Determine when the sun is up the latest. Estimate the date.

Will her graph ever hit a time of 0? You may need to extend the times below 10:30 pm.

Does the graph have a repeating curve shape? What functions look similar?
