Answer:
It will be in the air until P(x) is zero.
P(x) = -16x2 + 32x = -16x(x - 2)
P(x) = 0 ⇒ x = 0 or x = 2
It starts on the ground at x = 0, so the total time in the air must be x = 2 seconds.
Domain- -2>x<2
Range- [4,∞)
Increasing-[∞,4]
Decreasing-[4,∞]
It is a polynomial of doom. mwahahahah, you cant stop me spider man
