The velocity of a particle moving along a line is graphed to the right on a unit grid. At what value(s) of does the particle change direction? t Positive values of indicate that the particle is v traveling to the right, while negative values indicate that the particle is traveling to the left, so places where it switches sign (by passing through 0) indicate that the particle has changed direction. This occurs at , -4, and 9.
