The shape of a roller coaster is modeled by a polynomial function, R(x). Describe how to find the x-intercepts of R(x) and how to construct a rough graph of R(x) so that the engineer can predict when there will be no change in the direction of the coaster. You may create a sample polynomial of degree 3 or higher to use in your explanations.

To find the x intercepts, set y=0 and solve for x. For polynomials, that typically involves factoring.

So..?

anonymous · Answer

What equation should I use?

joannablackwelder · Answer

It doesn't give you an equation, so you can just make up a polynomial if you want. But you can describe how to do it without an equation.

Any suggestions?

joannablackwelder · Answer

I think it would be better for you to give it a shot and let me know.

anonymous · Answer

Just give me the answer
is it that hard to
