2 things
#1 - I am going to attempt this week to try to present the work through a video that I will post through youtube, if it works, it may allow me to explain things better than I think I have (though I will still pretty much be doing out all of the work...)
#2 - The Meriden school system doesn't have school on Friday, if they are not the only one's would anyone like to join me on skype to workout the homework? (I have already completed 1a and 1b and will hopefully be posting it through #1.
please, if you can, comment on this post with your skype name so I an others in the class can have it

Gonna try Skyping for homework help
add me on Skype: phillip.mangiaracina
we're going to try for a night or two to chat together. I can share my screen and we can share ideas on how to complete the homework.

Using Wolfram Alpha to get your answers! (HMWK4)
Sorry for the late working, I have been busy (I think... I don't know where the time went)
anyway, I did some searching for a way in which to use WolframAlpha to find the end results. The form is:
Fit[{ (x1, f(x1)), (x2, f(x2)),... (xn, f(xn))}, {1,x, x^2, x^3... x^j}, x] (j is the maximum degree polynomial.
the result for #1 is
THIS
which spits back
0.0208333 x^3-0.2 x^2+0.864167 x+0.005
this can be entered into excel with the x's replaced with the x-values and you will return the exact answer you are looking for, then you can place the xi's (the unknown x's) and you will see what you should expect to get spit back out.
the values look to be a bit off, but within reason...
hope this helps
again, sorry for it taking me so long to get on it
