Consider the following rational functions:
- (a) Which of these rational functions has a horizontal asymptote?
- (b) Which of these functions has a slant asymptote?
- (c) Which of these functions has no vertical asymptote?
- (d) Which of these functions has a “hole”?
- (e) What are the asymptotes of the function r(x)?
- (f) Graph y = u(x), showing clearly any asymptotes and x- and y-intercepts the function may have.
- (g) Use long division to find a polynomial P that has the same end behavior as t. Graph both P and t on the same screen to verify that they have the same end behavior.
