Answer:
Average rate of change between x = 3 to x = 5 is 0.
Explanation:
Given quadratic function s passing through two points (3, 0) and (5, 0).
Average rate of change of a function between x = a and x = b is given by,
Average rate of change =

From the graph attached,
Average rate of change between x = 3 to x = 5 will be,
=

=

= 0
Therefore, average rate of change between x = 3 to x = 5 is 0.
