Answer:
Pretty sure the first one is no cuz ive never seen a function curved like that
Step-by-step explanation:
H(t) = -16(t^2) + 64t
roots:
0 = -16t^2 + 64t
0 = t^2 - 4t
0 = t(t-4)
t=0 and t =4
The symmetry axis is at the middle of the two roots: t = (0+4)/2
That time (t=2) is what it takes the object to reach the maximum height.
Answer: t = 2; it takes 2 seconds to reach the maximum height and 4 seconds to fall back to the ground
