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.

how do you find the x intercepts of any polynomial?  for axample:  ax^2 + bx + c  is a polynomial

if you have a picture of a rollaercoaster, its even simpler .... place a grid over it and estimate the intercepts ... from that you can then construct a polynomial from the roots
