Given:
Step-by-step explanation
Step 1.
When the derivative is positive, the particle is travelling in a positive direction. We should test one point in each region surrounded by the points to see which of these regions is positive, since we know all sites where the velocity is equal to zero.
We don't need to care about this region because the function for t<0 is undefined.
For , test the point :
So in this region the particle's motion is negative.
