Answer 4

As one of the new roller coaster engineers, you have been tasked with developing a roller coaster that will intertwine with existing Oakville Lake Amusement Park structures. For one of the more thrilling sections, the roller coaster will dive down in-between buildings, plummet underground, pop back up, and coast over a hill before shooting back underground. There must be three distinct points where the roller coaster crosses the x–axis. Precise measurements and attention to detail are very important.
coordinate plane with buildings blocking off x–intercepts of negative 11, negative 10, 0, 1, 2, 3, 9, and 10

First, here is the existing map of current structures. It is important that the roller coaster does not go through the foundation of any of these structures.

1st point: ___6___
2nd point:___-2___
3rd point: ___-7___

Using the points above as zeros, construct the polynomial function, f(x), that will be the path of your roller coaster. Show all of your work.



Using both fundamental Theorem and Descartes` rule of signs, prove to the construction foreman that your funtion matches your graph. Use complete sentences.



Solve for the y–intercept for your function, f(x), and then construct a rough graph of your roller coaster. If your y–intercept is off the graph, give the coordinates of the y–intercept.

Answer 29

k, hold on

Answer 30

that on is different becuase that one he can choose his points, mine are set

Answer 31

hey math can here you say that

Answer 32

one*

Answer 33

Can any of the people I tagged help? *_*

Answer 34

this math is impossibru

Answer 35

@johnweldon1993 @jigglypuff314

Answer 39

can u help @johnweldon1993

Answer 40

I can, just looking at something sorry

There is a picture that accompanies this am I correct?

Answer 41

yes

Answer 42

Could you attach that for me?

Answer 43

im on an flvs website. the link is locked

Answer 44

Answer 45

can you see the picture

Answer 46

Nope, but after looking through the conversation so far, that link provided above by @HailKK does the picture in that question match yours? or is it different?

Answer 47

yes but with no lines on the graph. just the buildings

Answer 48

Okay thats fine, actually funny because I answered this question a while back as well

http://openstudy.com/study#/updates/529b7da9e4b0e39d4e829521

Now you are correct in the fact that they are different because your points are fixed, however the solving process is identical...take a look at what my answer was on this link and see if that helps at all...if not...just say so and I'll be more than happy to help :)

Answer 49

k thanks

Answer 50

@johnweldon1993 I still have no clue, all I got was what the graph was supposed to look like

Answer 51

Alright, so your fixed points are

x=6, x=-2 and x=-7 correct?

Answer 52

yes sir

Answer 53

Alright so what that means is your function, whatever that may be, will pass through those points on the 'x' axis

Sidebar real quick...Let me ask you, if we have the function x^2 - 1...that looks like



or something like that lol

Answer 54

What are these points here...?
