The graph which shows the velocity of the particle at any time is attached below.
<h3>How to depict the graph?</h3>
The graph is the rate of change of position of an object with respect to time. Velocity is the speed of an object moving in a definite direction.
Velocity is a vector quantity as it has both magnitude and direction. The velocity of a particle is modeled by the function. It is observed that the given velocity function is a cubic function. The attached graph shows the velocity of the particle at any time.
The range is simply the highest number minus the smallest number. Since we are told that 2 members of the family have shoe size of 7 and the range is 5, then Melissa shoes size will be:
