Answer:
It travels for 1 hour, then stops for 1 hour, and finally travels again for 3 hours.
Step-by-step explanation:
Distance changes over the first hour of travel, but then doesn't change for one hour, and then it continues on for the next three hours
U r going to subtract 3 from each side of the equation....leaving you with :
x^2 + 2x = -3
The parabola opens down, since the 'a' value of the equation is a negative value.
