Question 1125762: consider the function f(x)= -5x^3
-Determine the average rate of change (ARoC) of f over the following intervals of x.
a. From x=2 to x=2.5, whats the average rate of change?
b. from x=2.5 to x=3, whats the average rate of change?
c. from x=3 to x=3.5, whats the average rate of change?
-Consider the three average rates of change you computed in part (a). Are these average rates of change increasing, decreasing, or some combination of both?
-Over the interval from x=2 to x=3.5, does f have positive concavity, negative concavity, or some combination of both?

Given a function )
, the average rate of change from 
to 
is equal to the slope of the line through \))
and \))
, which is calculated by:
\ -\ \phi(x_a)}{x_b -\ x_a})
Your parts a, b, and c are just three arithmetic problems. You can use a calculator just as well as I can.

My calculator said it, I believe it, that settles it
