First make sure the expression is correctly transcribed:

2x/x-3

does not equal

2x/(x-3).

I suspect it's the latter you need.

Because of the lack of typesetting capabilities, parentheses are required around the numerator and the denominator.

Hints for asymptotes and domains:

1. All polynomials have a domain of R, or (-∞,∞).

2. Horizontal asymptotes are finite values to which the function approaches when x→±∞.

3. Vertical asymptotes for a rational function (i.e. polynomials in both numerator and denominator) occur when the denominator equals zero.

4. The domain of a rational function is therefore (-∞,∞)-points at which vertical asymptotes occur.

Post your answers for checking if you wish.
