please mark me as brainliast
First graph it
#1
Maximum height is the y coordinate of vertex
Max height
#2
Time is the x coordinate of vertex
#3
![\\ \rm\Rrightarrow -16t^2+64t+80=0](https://tex.z-dn.net/?f=%5C%5C%20%5Crm%5CRrightarrow%20-16t%5E2%2B64t%2B80%3D0)
x intercepts are the solutions
Take it positive
#4
put in function
- y=-16(1)+64+80=-16+144=128ft
