Respuesta :

Part A  the new  function will be -16t^2 + 224t + 120  

Part B  The axis of symmetry ( x = 7) will be same for both graphs
The maximum  value  fr the new graph will be 904 seconds ( that is 120 more than the original graph).
The zeroes for the first graph are 0 and 14.  For the second graph  the first one will be negative and the second will be greater than  14 meters.
c.From the ground
f(7)=-16*7² +224*7=784 ft 
If from 120 ft building - 784+120=904 ft
d.  -16t(t-14), t=14 , to increase by 2 sec, 
-16t(t-16)=-16t+256t
To make stay in the air longer by 2 sec , the initial velocity should be 256 feet/sec, if the company will be launching firework from the ground
