Question

Hi everyone! :) Can you please help me with some of my work?! I started it and read over it and just need a few explanations. Just a little push start would be so greatly appreciated! I know i'm missing something from my lesson...idk what but it must have been important xD lol !

Answer 1

First, here is the existing map of current structures. It is important that the rollercoaster does not go through the foundation of any of these structures. Pick three points on the x–axis that the rollercoaster will dive underground or resurface. (Points that have a building on them are off-limits.)

Answer 2

I did this part....
1. The rollercoaster will run from right to left, so work in that order when selecting points.
1st point:__(-6,6)____
2nd point:_(0,6)_____
3rd point:_(6,6)_____

Answer 3

2nd point is (0, -6) **

Answer 4

but i need help with this part :((
2. Using those points as zeros, construct the polynomial function, f(x), that will be the path of your rollercoaster. Show all of your work.

(now I know..or believe...that this is just f(x) = something....but how would I make this?)

Answer 5

Oh this seems like a fun question, but I really have no time to help you, sorry. But if it helps, the amount of times it can cross the x-axis is equal to the highest degree of x.

Answer 6

Thank you. It helped a little. :)

Answer 7

If you can imagine the graph of f(x)=x^2, it can cross the x-axis twice with the right conditions, but not all the time. It needs to be positioned so the minimum is below y=0.

Answer 8

So, that is going to help when making the polynomial function for part 2?

Answer 9

my Y needs to = 0

Answer 10

You would make the equation so that at whatever x you want y to be 0, y=0

Answer 11

oh okay. :) still a little confused but you are helping. do you know how i would take the 3 points and make the equation tho?

Answer 12

It's been so long since I did this, so I don't think I'd be of much use. I might say something incorrect, so I'll be safe and refer you to someone else.
