For this case we have the following expression:
 h (t) = -16t ^ 2 + 64t + 80
 For t = 0 we have:
 h (0) = -16 (0) ^ 2 + 64 (0) + 80
 h (0) = -0 + 0 + 80
 h (0) = 80 feet
 Therefore the number 80 represents the initial height of the rocket
 Answer:
 
the 80 in the expression represented:
 
the initial height of the rocket
