a point p moves along the axis so that its position x at t is given by x=t^3-4t +1
a)find the velocity and aceleration of point P at time t
b) determine the following
the tim interval on which the point is moving to the right
the tim interval on which the point is moving to the left
the acleration at times when the velocity is zero
the average verlocity over the time interval [0,4]
