The temperature in Virginia Beach depends on the number of days since Jan. 1, 2017.

(a) In the function described above, there are two variables: the number of days since Jan. 1, 2017 and the temperature in Virginia Beach. Which is x, and which is y?

Temperature in Virginia Beach is y

The number of days since Jan. 1, 2017 is x

(b) What would you expect the range of the function to be if the domain is [0,365]? You can either use interval notation or describe the interval in words.

(c) Sketch what you would expect the graph of the function to look like with domain = [0,365]. Label the axes with their units of measurement (days or degrees F)

(d) What would an x-intercept of the function tell you in terms of time an temperature? Would you expect such a point to exist? Why or why not?

(e) Where do you think the function would be increasing? You can either use interval or notation or describe the interval in words. Why?

(f) Where do you think the function would be decreasing? You can either use interval notation or describe the interval in words. Why?
