Question 862071
h (t) =224t-16t^2

a) no clue what 8768 means
16*548=8768
2^6×137=8768
b)
528 =224t-16t^2
at t=3 and t=11
c) 
0 =224t-16t^2
at t=0 and at t=14
d)
h(t) =-16t^2+224t

-b/2a
224/32=7 at t =7 it reaches its maximum height
e) max height is 784 at t=7
f) domain : all real numbers
range : real numbers where y<=784}
