Part 2: Designing a roller coaster
Look at the polynomial below.
y = ax3 + bx2 + cx + d
Graph this using any graphing technology of your choice. However, replace the variables a, b, c, and d with numbers. For example, you could graph y = 2x3 + 3x2 – x + 2. Observe the graphed outcomes. This is an investigation process to see what types of curves and lines you can produce with this equation.
Special Note: You may make any coefficient zero. This eliminates the variable. For example, if you wanted to make y = 3x2 + 2, a and c would be zero to cancel out the x3 and the x terms.
Select GeoGebra if you would like to use a graphing interactive to complete this part of the project.
A. Graph different functions by changing a, b, c, and d to “design” your ideal roller coaster. Come up with at least four equations that, when pieced together, would make your ultimate roller coaster. Be sure to note what window sizes you’re using in your graphs. You may have to change the default size to better see each of the polynomials’ shapes.
B. Use a drawing program (or draw by hand and scan) to recreate your roller coaster, and for each section, provide the equations you decided upon.

OK I asked for your help on MY question. You said to post it in the chat area and tag you. I did. Then you opened up YOUR own question. I don't understand what your plan is or what your trying to do.

Well it won't let me put a long retricequestion where I put "need help" I don't understand him!

- muscrat123
