Question

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.

Are there one or two possible solutions to this problem? How do you know?

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.)

Answer 1

angry birds is your game, but you can use other functions other than a parabola.
horizontal line - straight across
vertical line-up
how about the grey little bird that breaks up into 3 birds

Answer 2

now if you are solving that particular quadratic, just use the quadratic formula

Answer 3

ok, I know nothing about the game angry birds, so I am totally lost with that part. This week we are studying parabola so I think that is the way that I shoud figure this out or am i wrong on that?

Answer 4

so you made up the equation?

Answer 5

I am trying as hard as I can to get this right, if I don't I'm going to flunk my mat/117 class and I don't want to fail
yes the equation is y = - b/2a, which is -(4)/2(2) = -1
2(-1)^2 + (-4) + 3 = 3

Answer 6

that is the vertex? Is that what you are looking for?

Answer 7

this is a max point

Answer 8

I found the vertex and the line of symmetry, now I need to find out the flight, left to right, of the bird, and I'm lost on that one

Answer 9

use the quadratic formula

Answer 10

plus i need to figure out if there is one or two solutions, I'm thinking that there is only one, am I right?

Answer 11

you meant instead of the formula I said before?

Answer 12

well solutions mean how many times it crosses the x axis

Answer 13

I would call it two
