Question

Very tough question that I am completely clueless on how to do. "phi" done #1 but I don't know how to do the rest.

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.)

The rollercoaster will run from right to left, so work in that order when selecting points.
1st point:______
2nd point:______
3rd point:______


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


Using two of the theorems dicussed in the lesson, prove to the construction foreman that your function matches your graph. Use complete sentences.


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


Two competing engineers have offered their solutions for the function. One has suggested g(x) = x3 – 2x2 + 4x – 8, and the other has suggested h(x) = x3 + 5x2 – 8x – 48. Explain to the C.E.O. of Oaville Lake Amusement Park why these other suggestions are invalid. Use complete sentences.

Answer 2

Ive done #1.
1st point: 5
2nd point: -4
3rd point: -13

Answer 3

Don't you mean *I* did #1. That is my graph.

Answer 4

yeah pretty much plagarised that hahah

Answer 5

this stuff is tough for me :/

Answer 6

download geogebra
see http://www.geogebra.org/cms/en/

any type in some functions and you can see what is going on.

Answer 7

@phi i have geogebra now. could you help me with this question?
