The shape of a rollercoaster 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 to be used in your explanations.

Well, a rollercoaster has it's peak. So it goes from low, to high, to low...

i need and sample polynomial to be used in your explanations.  @abb0t

abb0t · Answer

There's a few choices you have: $\sf x^2~ and ~x^3$

anonymous · Answer

ill choose x^2 @abb0t

abb0t · Answer

Do you know what the graph of x$^2$ looks like?
