times throughout a 24-hour period and records her findings in the graph below. In this
real-world function, the hours represent the input values, and the temperature represents
the output values. Use the graph to identify the range of the function. Write your answer
as a set of ordered pairs. Then write a sentence to explain what the range represents in
this function.
