When the denominator is equal to zero, the expression is undefined. Close to those places, the expression tends towards plus infinity, or minus infinity. In other words, setting the denominator to zero will tell you where there are vertical asymptotes.
When you graph a tangent function, the asymptotes represent x values 90 and 270.
Not sure what non-verticle means, but a rational function can have up to 2 non-vertical asymptotes,
No, it will always have one.
The answer depends on the form of the expression in the denominator. For example, the graph os 1/(1 + x2) has a pretty well-behaved graph, with a maximum vaue of 1 when x = 0 and asymptotes of y = 0
