Let f(x) = 3(x^4+x^3+x^2+1)/(x^2+x-2). Give a polynomial g(x) so that f(x) + g(x) has a horizontal asymptote of 0 as x approaches positive infinity.

If you could give me the answer to this question quickly, that would be very helpful. Thanks!

I think that there is something wrong with your question.

That division has a remainder .....

But Alan

3(x^4+x^3+x^2+1)/(x^2+x-2)

does not divide to give a polynomial so how can you say that this question makes sense. ?

The question doesn’t say that f(x) is a polynomial; it just asks for g(x) to be a polynomial, and for the limit of the sum of the two functions to have a zero asymptote.

Well it doesn't make sense to me, it says that division gives a polynomial g(x)

"Let f(x) = 3(x^4+x^3+x^2+1)/(x^2+x-2). Give a polynomial g(x) so that f(x) + g(x) has a horizontal asymptote of 0 as x approaches positive infinity."

Was this the intended question?

Let f(x) = 3(x^4+x^3+x^2+1)/(x^2+x-2).

Find a polynomial g(x) such that f(x) + g(x) has a horizontal asymptote of 0 as x approaches positive infinity.

I don’t think it says division gives a polynomial Melody! There is a full stop (period) between the function definition and the word Give (which also starts with a capital letter), so I interpreted the sentence beginning with Give as an instruction to the reader, not a continuation of the previous sentence.
