NO ONE IS HELPING ME :( The height, h, of a stomp rocket (propelled by a short blast of air) above the ground after t seconds is given by the equation h(t)=5+100t−16t2. Here is a graph that represents h.
1. What does the 5 in the equation represent?

2. What does 100t in the equation mean in terms of the rocket?

3. Approximately when does the rocket hit the ground?

4. What domain makes sense for the function in this context?

Given equation and the graph of it:

1. What does the 5 in the equation represent?

2. What does 100t in the equation mean in terms of the rocket?

3. Approximately when does the rocket hit the ground?

4. What domain makes sense for the function in this context?

Domain of the function is:

This is the time the rocket is in the air until it hits the ground

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.
