Question

Please Help! Medal to best answer!!! =D

Answer 1

A. 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.
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.
B. 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.
C. Use a drawing program to recreate your roller coaster, and for each section, provide the equations you decided upon.

Answer 2

This graph should be the same as the graph of x^3. Plug it into a graphing calculator or software. I used https://www.desmos.com/calculator and got this. Good luck!

Answer 3

I use graphmatica but you have to download it. I find it very useful!

Answer 4

Okay, thanks! I'll look it up. :)

Answer 5

@smileandcanter Is it like GeoGebra?

Answer 6

yeah kinda
