1. 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.

Find the verticle, horizontal, and oblique asymtopes if any. #1 (x^2 +6x+5)/2x^2 +7x+5 y= (1/2) and x= -5/2 and -1 #2 (8x^2 +26x-7)/4x-1 y=2x+7 and x=1/4 #3. (x^4-16)/(x^2-2x) x= 0 and 2 y= x^2 +2x+4 thanks!
