Question

Help with polynomials please?? :)

Answer 1

The roller coaster will run from right to left, so work in that order when selecting points.
1st point: (8,-4)
2nd point: (-2,6)
3rd point: (-5,-10)



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



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



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



4) 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 Oakville Lake Amusement Park why these other suggestions are invalid. Use complete sentences.
