The average rate of change of the function over the interval [-1, 2] is: C. 2.5.

<h3>How to Find the Average Rate of Change?</h3>

The average rate of change over an interval of a function is: f(b) - f(a) / b - a.

Given the interval [-1, 2]:

a = -1; f(a) = -5

b = 2; f(b) = 2.5

Average rate of change = (2.5 - (-5)) / (2 - (-1)) = 7.5/3

Average rate of change = 2.5 (option C).
