The function above represents the displacement of a toy race car as it travels a linear track. Negative numbers mean the car is behind the starting line, positive numbers mean it is in front. Postive velocities mean it is moving forward, while negative velocities mean it is moving backwards.
Remember that a value which changes from -2 to -1 to 0 is increasing!
For each interval, enter all letters whose corresponding statements are true for that interval.
1. The interval from a to b
2. The interval from b to c
3. The interval from c to d
4. The interval from d to e
5. The interval from e to f

A. The car is in front of the starting line on this interval
B. The car is behind the starting line on this inteval.
C. The velocity of the car is positive on this interval.
D. The velocity of the car is negative on this interval.
E. The displacement of the car from the starting line is increasing on this interval.
F. The displacement of the car from the starting line is decreasing on this interval.
