    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: f(t) = −16t2 + 34t + 80 The average rate of change of f(t) from t = 5 seconds to t = 7 seconds is _____ feet per second.

    A basketball is thrown upwards. The height f(t), in feet, of the basketball at time t, in seconds, is given by the following function: f(t) = −16t2 + 94t + 12 Which of the following is a reasonable domain of the graph of the function when the basketball falls from its maximum height to the ground? 2.9375 < t < 6 2 < t < 5 1 < t < 4 0 < t < 3
