Question

NEED MATH HELP PLEASE!!

Answer 1

You and Rachel are going to create a Roller Coaster together. Graph ax^3+bx^2+cx+d 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.
Rachel has already completed this

Answer 2

Rachel has already completed this part, and she has come up with the following 2 equations she would like to see in your roller coaster:
-2x^2+7x-4 & 3x^3+3x^4=10
Graph both of these equations and see what they look like. Now you add two more equations (making it a total of 4 equations) to create your roller coaster.
Use a drawing program (or draw by hand and scan) to recreate your roller coaster, and for each section, provide the equations you and your partner decided upon.
Using complete sentences, describe the theme of your roller coaster (example: monsters), and give your instructor details as to what your roller coaster would look like, feel like, and what makes your roller coaster unique.

Answer 3

A hundred years ago, when I first started studying calculus, we graphed by hand. If you only graph with software, I could show you how to get relative min and max, real zeros, asyptotes. Otherwise, a graphing calculator or software like Maple is a good way to go. There is some free graphing websites that are pretty good also.

Answer 4

I dont know how to do it...

Answer 5

If you are using that first example equation, y = 2x3 + 3x2 – x + 2, if you are able to do so, you could start by getting the first and second derivatives. Can you do that? What course are you in?

Answer 6

I dont get the whole assignment

Answer 7

What course are you in?

Answer 8

im in Algebra 1

Answer 9

This is a big assignment for Algebra I !!! All right, I can't show you the theory of what I was initially going to do because it requires a lot more math from higher levels. We had better stick to graphing websites.

Answer 10

Okay. I still dont know what to do for this though..

Answer 11

It will be just fine. No worries. We'll just go to a graphing website and the computer will do all of the work.

Answer 12

but what do i put into the computer? And what about the other things i have to make??

Answer 13

D: I am really dumb when it comes to math.... :[

Answer 14

Well, the stuff about roller "theme" and "monsters" is just an attempt to make it fun through simulating a real roller coaster. For that part, we can use our imagination. The whole assignment obviously has to be mathematical and I suspect that the sharper "curves" are supposed to make the "ride" more thrilling. Keeping it mathematical for now, we can look at how the curves get "curvier". It could be fun.

Answer 15

I just went to a free graphing website that I was never at before and it took almost no time to figure out how to use it. That in itself can be lots of fun. Kind of like a video game that you have total control over.

Answer 16

You might want to open up a separate window and go to http://www.meta-calculator.com/online/

Answer 17

I just graphed y = 2x3 + 3x2 – x + 2 at that site. You have to enter (without the "y =") 2*x^3 + 3*x^2 – x + 2 . It looks like this and the whole thing is very handy:
