Question 354803: If I have given information such as vertical and horizontal asymptotes, x and y intercepts, or a graph, how do I find the rational expression?
I know that to find the denominator, I use the vertical asymptotes. For the numerator, I use the x intercepts.
What would I do with the horizontal asymptotes or y intercepts?

Recall that the horizontal asymptote of is . Example: the horizontal asymptote of is

To find the y-intercept, simply plug in x=0 to find y. So when constructing the function, make sure that f(0)=b where 'b' is the y-intercept. Ex: If you're given a y-intercept of 2, then make sure that f(0)=2

If this info seems a bit vague, post the actual problem so we can help.
