If you long divide you get:
Therefore, f(x) approaches the line y=ax+b as x increases or decreases without bound.
Hence, your asymptote is
Hi all,
I'm currently having the hardest time understanding how to find the Oblique Asymptote.
An example is x^2 -1 / x + 3. I know I have to use long division method to figure this out but I don't even know how to start on such a simple one as this. Can someone give me a detailed method of doing this? Thanks alot~
Oh. I would suggest getting an algebra book and practicing. You really should be able to do that at this level.
But here goes this one:
So, you have:Code:x -3 ____________________ x+3|x^2 -1 x^2+3x --------------------------- -3x-1 -3x-9 ------------------------------- 8
It works just like other division.
