The function h=-16^2 + 1000 gives an objects height, h, in feet, at t seconds.

1.does the constant 1000 tell you about the height of the object?
2.when will the object be 1000 feet above the ground? How did you find that answer?
3. How many seconds did it take the object to hit the ground? How did you find this answer?
4. What is the maximum height that the object reached? How many seconds did it take to reach that height ? How did you find the answer?

And it starts at 0 thrown up till 1000 feet down back to 0, so it’s not thrown off amount of height
