answer: the average rate of change of f(t) from t = 3 seconds to t = 5 seconds is -40 feet per second.

step-by-step explanation: xx

given: a ball is thrown upward from the top of a building. the function below shows the height of the ball in relation to sea level, f(t), in feet, at different times, t, in seconds:

now,

now, the   average rate of change of f(t) from t = 2 to t = 6 is given by : -

therefore, the average rate of change of f(t) from t = 3 seconds to t = 5 seconds is -40 feet per second.
