2. The graphs of three different rational functions are shown. a) Compare the degrees of the numerator and denominator for the rational functions represented by each of the following graphs. b) Determine whether there are any common factors in the numerator and denominator, and give the x value(s) where these occur. #1 #2 #3 1043. Explain why the graph of the function f(x) = x-2 3 crosses the x-axis at the point X (2, 0), but also has a horizontal asymptote at y = 0
