Explanation:
Previous concepts
The range of a set of data is "the difference between the largest and smallest values of this dataset". Using this definition the formula for the range is:

We assume that the minimum value for the temperature on this case is -9F , so then:

And we assume that the maximum value occurs at the afternoon, and on this case then:

Solution to the problem
And then using the definition of range we got:

So then for the question :"What is the range between the high and low temperatures of the day?" We can answer 33 F
