98 points brainliest ! a ball is thrown 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: f(t) = -16t^2 + 32t + 90 the average rate of f(t) from t = 4 and t = 6 seconds is seconds. i think the answer is -128 ft per second. if that's right let me know and if it's not explain what you did.
