The figure shows the graphs of three functions. One is the position function of a car, one is the velocity of the car, one is its acceleration, and one is its twitch. Identify each curve.

Answer by Guest

a) Is the twitch - initial positive twitch or sudden movement, which is what
makes the car jolt into action.

b) is the acceleration - graph shows the acceleration and
deceleration of the car.

c) is the velocity - starts at 0 and increases until the car
travels at its right speed.

d) is the position - assuming that the car is going on only
one direction. This graph is the only one that does not go back to the x-axis.
