Answer:

A. The third rocket is launched at 6 seconds.

B. It approximately lands at 7.25.

C. All rockets are in the air from 6 seconds to 7.25 seconds.

Explanation:

Remember that the x value represents the time.

A. The third rocket is launched at 6 seconds. We can tell because the third curve starts at x=6.

B. It approximately lands at 7.25. We can tell because the first curve reaches a height of zero (y=0) when the x value is in between 7 and 8.

C. All rockets are in the air from 6 seconds to 7.25 seconds. We know this because the third rocket is not launched until about 6 seconds, and the first rocket lands at about 7.25 seconds. So all three are in the air in between that that time.
