If you can coherently type up with your delimma is, we might be able to parse it as well :)

There’s a game that I really enjoy playing where the object is to knock down various pigs with birds.  The cool thing about the game is that, in order to master it, you must have a solid understanding of parabolas.  
To knock down a certain pig, I think that my quadratic equation would be y= 2x2 + 4x + 3.
	 Will this parabola knock down any pig?  Why or why not?  (Hint: Graph it!) 

No it would not because the parabola is positive. 

	 Are there one or two possible solutions to this problem?  How do you know?

There would be two possible solutions in this problem. There are two points on the x-axis, since the parabola is going upwards there would be more than one solution.  


	What is the vertex of the parabola?
The vertex of the parabola is y =  (-(4))/(2(2))  = -1
2(-1) + 4 (-1) + 3 = 4 + (-4) + 3 = 3
The vertex is (-1, 3)

	The flights all will begin and end on the x axis.  Assuming that this is a flight, where does the bird begin her flight (assuming left to right flight)?  (Round to the nearest hundredth, if needed.)



	Assuming that this is a flight, where would the bird end her flight?  (Round to the nearest hundredth, if needed.)


After a few tries, I pass that level with 1 star.  (I never said I was good at the game.)  So, I am onto the next level.  I determine to slay another of my enemies, the equation would be y= -x2 -2x + 6.  
	 Would this parabola knock down any pig?  Why or why not? (Again, with the graph…)



	 Suppose that the pig is sitting on the x axis of a coordinate plane.  On a coordinate plane, where is the pig on the x axis, assuming that the bird is flying from left to right? (Round to the nearest hundredth.) 

	Assuming that this is a flight, at what point does my bird begin his flight, assuming that the bird flies from left to right?

	How high will my bird get at it’s highest point?   

	 Are there one or two solutions to this problem?  How do you know?

This is the worksheet that I am stuck on and could use all the help I can get on this.

can you explain your reasoning to this?

amistre64 · Answer

im not too sure what the "rules of the game" are.

anonymous · Answer

Since the parabola is positive, it would not be able to knock down anything

anonymous · Answer

neither am i that is why I am having such a hard time with this worksheet

zzr0ck3r · Answer

can you draw a picture of the "game"

anonymous · Answer

http://www.angrybirdsnest.com/ham-em-high-3-star-walkthrough-facebook-level-3/ this is the website that I was given earlier.

amistre64 · Answer

the parabola defined is a curve on a graph; unless the "pig" is someplace along that curve, it would never touch it is my thought; but i dont know the rules perse

anonymous · Answer

no i do not know anything about it except for what is on the website

amistre64 · Answer

hah, angry birds

anonymous · Answer

yes, i know nothing about that game

zzr0ck3r · Answer

im thinking like angry birds yeah

anonymous · Answer

yes

amistre64 · Answer

what is spose to be the "origin" to map the parabola with?

anonymous · Answer

the equation $$y= 2^2 + 4x + 3$$

anonymous · Answer

opps did that wrong, it is $$y= 2x^2 + 4x + 3$$

anonymous · Answer

the vertex is (-1,3) and the line of symmetry is 3

amistre64 · Answer

that can be drawn on a graph; but you would have to determine the crossing point of your axises;  where they cross is called the origin, and is the point (0,0)

without knowing how to position the "graph" to the playing feild of the game, the rest of it becomes rather moot

anonymous · Answer

i know that is what has me stumped

amistre64 · Answer

srry, but i dont think i can be of much help using this type of format ..... :/

good luck with it tho.

anonymous · Answer

ok thank you
