We have been given a graph and table of data about recorded temperatures outside Gale and Hector's homes.
We can see from graph that at noon temperature outside Hector's home is 3 degree Fahrenheit that is h(0). Our table shows the temperature outside Gale's home at noon is -1 degree Fahrenheit that is g(0).
Let us find the difference between temperatures outside Gale and hectors home at noon.
We can see that at noon temperature outside Hector's home is 4 degree Fahrenheit more than temperature outside Gale's home.
Therefore, at noon, temperature outside of Hector's home was warmer than temperature outside of Gale's home.
The range of a data set is the difference between the greatest and least values in the set. In this case, the greatest value is 15 and the least value is 2 so the range is 15 - 2 = 13.
