I have this problem with equation h=15+20t-2t^2 object throwen from tower
I must making graph to show time of flight
Then show greatest height reached.
How high is building
And how long did it take for object to hit.
1 I thinking for graph formula must be xv=-b/2a
which is -20/-2x2=-20/-4=5 this is for my x.
can you please showing me how for getting my y .
when i am knowing this i think i can do rest of problems,
