Question

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

Answer 2

I just need help with the 2nd one

Answer 3

uhhh one sec. I gotta think kinda far back. It's been forever since I learned the fundamental theorem and Descartes' rule of signs

Answer 4

OK np

Answer 5

The fundamental theorem of algebra states that every non-constant single-variable polynomial with complex coefficients has at least one complex root. This includes polynomials with real coefficients, since every real number is a complex number with an imaginary part equal to zero.

Answer 6

So this is the theorem using the p's and q's?

Answer 7

http://mathworld.wolfram.com/DescartesSignRule.html there's the descartes' rule of signs and ummmm

Answer 8

and no... that's the rational root theorem

Answer 9

does that make sense?
