**Section 3.6:**

1. Let \( f(t) = 24t - 4t^2 \) for \( 0 \le t \le 8 \) be the position function of an object moving horizontally along a line after \( t \) seconds.

    **a)** Graph the position function.

    **b)** Find and graph the velocity function. When is the object stationary? Moving to the right? Moving to the left?

    **c)** Determine the velocity and acceleration of the object at \( t = 3 \).

    **d)** Determine the acceleration of the object when the velocity is zero.

    **e)** On what intervals is the speed increasing?
