Idon't understand how to solve this one. quality will get brainliest! i think the answer is a, but i'm not entirely sure why.

That would be (x + 3)(x - 4)

- because the 2 zeroes are -3 and 4.

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.
