Using the index "n" of the partial sums of a series as the domain, and the value of the corresponding partial sums of the series "Sn" as the range, is a series a function?

Include the following in your answer:

Which one of the basic functions (linear, quadratic, rational, or exponential) is related to the arithmetic series?
Which one of the basic functions (linear, quadratic, rational, or exponential) is related to the geometric series?
Give real-life examples of both arithmetic and geometric sequences and series. Explain how these examples might affect you personally.

F(y) = [(1/y^2) - (3/y^4)] (y+5y^3)

this becomes F(y) = [1(y^-2) - (3(y^-4)] (y+5y^3)

this is what I've solved so far:

F ' (y) = [-2(y^-3)+12(y^-5)] (y+5y^3) + [1(y^-2) - 3(y^-4)](1+15y^2)

I don't know if I've done this correctly at all !!!
The answer should be

F ' (y) = 5 + 14/y^2 + 9/y^4

Could someone please explain this to me. I am struggling taking an online calculus class but I am really making an effort to learn HOW to do the problems. I am just having a hard time with the algebra!

You suspect that your unknown contains halogen, so you perform the silver nitrate in ethanol test and the sodium iodide in acetone test, both of which are negative. Do these results prove that your compound does not contain halogen? Briefly explain.

Can anyone tell me the relationship between the number of speakers (or other sources of sound) and the sound level.

For example, if you had a speaker playing at max volume and recorded the volume at 70db, then played another identical speaker next to it at max volume. What would the increase in total decibels be?

(Sorry i'm not sure how to explain this question properly, but i basically want to relate it to people in the audience at a rock concert - basically to define how 60,000 people shouting at the same level sounds just a bit louder than 1 or 2 people shouting!!).

All you brainiacs out there, if light reflects off an object... then waht color is the object itself?

If white light contains all the colors of the visible spectrum, and say, it reflects off of an object that is red, the object itself absorbs all the colors of the spectrum except red. So then is that object in fact red? or is it every other color except red?

What about a 'black' light? if the color black lacks all colors, why then when you shine a black light on an object, it appears as it's 'negative' color, such as reds or yellows appear green. Not all colors but many colors exhibit this phenomenon. An object that is "white' in color glows almost flourscent in black light...

What is it exactly are we seeing when we see the 'color' of an object?

I am looking for your thoughts, not something you cut and paste out of a website or quote from a book.
