It's pretty heavy (Calc)

I'm sure my Algebra 2 mind can handle it.

Post it in the thread.

Yeah, post it here and we can all work on it.



Why not just post it here?



OK
Determne tthe following about the graph of the equation: y= 8/x^3 - 6/x
Is the graph symmetric with respect to: the x-axis, the y-axis, or the origin
Find all vertical/horizontal asymptotes
Find the x-coordinates of each point at which y has a relative maximum or minimum'
Find the x-coordinate of each point of inflection

Well that's simple, you just take the conjugate of the inverse matrix and divide by e to the power of a square slice of pie.

Ugh, I hate hitting the post button on accident

 

Anyway, let's see if I can help

Yes, but before that, you have to apply the Fundamental Theoretical Principle to analyse the trends in the data, thereby showing the asymptotic functions of the inverse.

Throw the equation in there (you have to remove the "y=")

That'll give you an idea of the answers, as for the rest...it's just applying the formulas. Find the first and second derivative of the equation, I don't remember the exact conditions of point of inflection, but I think it was Fx = 0 and Fxx = 0....I can't remember that exactly

With those two links you should be able to do most of it easy peasy.

 

Edit: Points of inflection can be found where f'' = 0

Asymptotes can be found by turning the equation into a whatdayacall it, when you have only a numerator and denominator, and then solve the top for zero which is your horizontal asymptotes and the bottom for zero which are your verticle asymptotes. By the looks of the graph they're about the origin though. At least I think that should work.
