A projectile is launched into the air from the ground. the table shows the height of the projectile at different times. Projectile Height
Time (seconds) Height (meters)
5-1,353
10-2,460
15-3,323
20 -3,940
25 -4,313
30- 4,440
35- 4,323

Based on the data shown in the table, write a function to model this situation. After approximately how many seconds will the projectile hit the ground? 30 seconds :

: f(2)=1.1(36496.7)" :
: f(x) = -4.9x2 + 295x + 0.6 :
: f(x) = 30.2x + 0.6 :
f(x) = 36496.7(1.1)" :
: f(x) = 0.63x + 30.2 ::
f(x) = -16x2 + 295x + 0.6 ::​
