Step-by-step explanation:
<u>Part A</u>
The average rate of change of a function over the interval
is equal to
, hence:

Therefore, the average rate of change of
over the interval
is
.
<u>Part B</u>
Do the same thing as in Part A:

Therefore, the average rate of change of
over the interval
is
.
<u>Part C</u>
To interpret our answer from Part B in terms of the real world it represents, we say that between 0.25 seconds and 1 second, the ball falls at a rate of 4 feet per second (since our average rate of change is negative).
