horizontal asymptote

Find the horizontal asymptotes of the function's graph

y = 200 / (1+10e^(0.5x))

If you let x --> minus infinty the exponential tends to zero and the function approaches 200. If x --> infinity then the exponential becomes infinite and therefore the limit is zero. So, the asymptotes are y = 200 and y = 0.

    Is it possible to roughly sketch a graph(without plotting the points) from the asymptotes of a rational function? Is yes, what are the rules? For example, if I have to sketch a graph of y = (2x^2+10x-12)/x^2+x-6), how do I do it?
