whats the question?
Give me a sec. Let me copy and paste
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. I need to get 4 different equations with the function above. I tried many times but it comes out wierd.
So, what have you gotten done so far????
I've done norhing. I just need the 4 functions and that's it. Then to graph them and make the "Rollercoaster"
Its's not a site to give you direct answers, there are other sites on the interne if you want only answers. Copy and paste what you've already done, and you'll have help. It's like with a teacher, if you don't show him what you tried to do, you won't have any help.
Ok, this question that I'm posting it's from a portfolio/file that I have. It's 3 questions. I already did question 1 and 3. I found the functions and all I needed was someone to graph them for me because I was having difficulty trying to do them. I don't know how to do it on paper and the functions came out wrong in any function grapher. I can't find the same exact answer on other sites which is why I come here for people to help me. I'm not the best at functions so if someone was willing to help me, I'm pretty sure I would've understood. But no one wanted to help. I posted this question like 3 times and yet like I said no one helped. So I had to send my file in like that. @PERCE-NEIGE
Did you try Khan Academy? They are very helpful there.
