Answer:
Explanation:
Without the graph, I cannot see the specific details of the situation, but I can provide a general explanation of what an x-intercept represents.
An x-intercept is a point on the graph where the function or curve intersects the x-axis. In other words, it is the point where the value of the function is equal to zero. In the context of a distance-time graph for a car traveling for 8 hours, the x-axis would represent time and the y-axis would represent distance.
If there is a second x-intercept on the graph, it means that the car has returned to its starting position for a second time. The first x-intercept would represent the time at which the car reaches its destination or turns back around, and the second x-intercept would represent the time at which the car returns to its starting position.
Therefore, the second x-intercept would represent the total time the car spent traveling, including the time it took to return to its starting position for the second time.
