MATLAB plotting problem

The position x(t) as a function of time of a particle that moves along a straight line is given by: x(t) = -0.1t^4 + 0.8t^3 + 10t - 70 The velocity v(t) of this particle is the derivative of the position function: v(t) = -0.4t^3 + 2.4t^2 + 10 Likewise, the acceleration a(t) of the particle is given by the derivative of the velocity: a (t) = -1.2t^2 + 4.8t Create one figure that contains all three of these functions vs t where 0 lessthanorequalto t lessthanorequalto 8. To plot these functions, use the plot command. Using the subplot command arrange the graphs into one column with 3 rows (Don't forget to include a title and axis labels.) Time Is in seconds; position Is in meters; velocity is in m/s; and acceleration is in m/s^2
