PLEASE HELP! Does the following relation represent a function? Why or why not? (-1,7) (-7,7) (17,7) (11,7)

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
