Given r(x) = (3x - 9) / (x + 2)

a. Find the x and y intercepts:

b. Find the vertical asymptote(s) and the behavior near asymptote(s) from both sides:

As: x --> y -->

x --> y -->

c. Is there a horizontal or slant asymptote (if there is a horizontal asymptote, where does the graph cross it)?

d. Sketch the graph of r(x) and label axes, asymptotes, intercepts, and test points (show at least 2 test points on each branch of the function's graph).
