T(d) is a function that relates the number of tickets sold for a movie to the number of days since the movie was released. the
average rate of change in t(d) for the interval d = 4 and d = 10 is 0. which statement must be true?

a. the same number of tickets was sold on the fourth day and tenth day.

b. no tickets were sold on the fourth day and tenth day.

c. fewer tickets were sold on the furth day than on the tenth day.

d. more tickets were sold on the fourth day than on the tenth day.

B

Step-by-step explanation:

This can be represented by a graph of; number of tickets sold against number of days since the movie was released.

y-axis should represent the number of tickets sold.

x-axis should represent the number of days since the movie was released.

d should stand for 'the number of days.'

If the average rate of change (slope of the graph) between d = 4 and d = 10 is 0, this means that zero tickets were sold between day 4 and day 10.

So the correct answer is B.
