Using quadratic function concepts, it is found that:
- It takes 1 second to reach maximum height.
- The maximum height is of 25 yards.
- It takes approximately 3.2 seconds for the rocket to hit the ground.
The height of the rocket <u>after x seconds</u> is given by:
Which is a quadratic function with coefficients .
The maximum height will be a reached at a time of , and will be of , considering the vertex given by:
Then:
Thus:
- It takes 1 second to reach maximum height.
- The maximum height is of 25 yards.
It hits the ground when , thus:
We want the positive root, so, it takes approximately 3.2 seconds for the rocket to hit the ground.

Answer with explanation:
We have to graph the Linear equation:
→ y-4 =x+2
⇒To draw a line you need two points that lies on the line.
→Point (-2,4) lies on the line,as
L HS→4-4=0
R HS → -2 +2=0
→From Point (-2,4) finding a point which is left 1 unit and down 3 units is equal to = (-2-1 ,4-3)
= (-3,1)
→And from Point (-2,4) finding a point which is left 3 unit and down 1 unit is equal to = (-2-3 ,4-1)
= (-5,3)
→None of the two points that is (-3,1) and (-5,3) lie on the linear function
which is, y-4 =x+2.
≡None of the option
