Given the function g(x) = -3x+1
Find x if g(x) = 16

If g(x) equals 16, then by replacing x with -5:

(-3•-5) + 1
15+1
=16

Which means that

x in g(x) equals -5

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.
