Consider the rational function, $y = f(x)$, shown in the graph given above.

a) Find $f(-3) =$

b) What are the vertical asymptotes of $f(x)$?
Note: If there is more than one, list each separated by a comma: "x=a, x=b".
Do not include spaces around the equals sign. Type, for example, "x=1", not "x = 1".
Answer:

c) If you were to continue the graph to the right, the graph would tend to look like a horizontal line. What is the equation for the horizontal asymptote?
