The graph shows the function f(x).

what is the function's average rate from x = 7 to x = 11.

enter your answer in the box.

As shown on the graph the 2 points mentioned have the following coordinates:

A(7,19) & B(11,11), That is A(x₁,y₁) & B(x₂,y₂)

the rate of change between A & B is the slope that is equal to:

slope = rate of change = (y₂-y₁) / (x₂-x₁) ==>(11-19) / (11-7) = (-8) / (4)

Rate of change = -2

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.
